Trait Display

pub trait Display {
    // Required method
    fn fmt(&self, f: &mut Formatter<'_>) -> Result<(), Error>;
}

Format trait for an empty format, {}.

Implementing this trait for a type will automatically implement the ToString trait for the type, allowing the usage of the .to_string() method. Prefer implementing the Display trait for a type, rather than ToString.

Display is similar to Debug, but Display is for user-facing output, and so cannot be derived.

For more information on formatters, see the module-level documentation.

Completeness and parseability

Display for a type might not necessarily be a lossless or complete representation of the type. It may omit internal state, precision, or other information the type does not consider important for user-facing output, as determined by the type. As such, the output of Display might not be possible to parse, and even if it is, the result of parsing might not exactly match the original value.

However, if a type has a lossless Display implementation whose output is meant to be conveniently machine-parseable and not just meant for human consumption, then the type may wish to accept the same format in FromStr, and document that usage. Having both Display and FromStr implementations where the result of Display cannot be parsed with FromStr may surprise users.

Internationalization

Because a type can only have one Display implementation, it is often preferable to only implement Display when there is a single most “obvious” way that values can be formatted as text. This could mean formatting according to the “invariant” culture and “undefined” locale, or it could mean that the type display is designed for a specific culture/locale, such as developer logs.

If not all values have a justifiably canonical textual format or if you want to support alternative formats not covered by the standard set of possible formatting traits, the most flexible approach is display adapters: methods like str::escape_default or Path::display which create a wrapper implementing Display to output the specific display format.

Examples

Implementing Display on a type:

use std::fmt;

struct Point {
    x: i32,
    y: i32,
}

impl fmt::Display for Point {
    fn fmt(&self, f: &mut fmt::Formatter<'_>) -> fmt::Result {
        write!(f, "({}, {})", self.x, self.y)
    }
}

let origin = Point { x: 0, y: 0 };

assert_eq!(format!("The origin is: {origin}"), "The origin is: (0, 0)");

Required Methods

fn fmt(&self, f: &mut Formatter<'_>) -> Result<(), Error>

Formats the value using the given formatter.

Errors

This function should return Err if, and only if, the provided Formatter returns Err. String formatting is considered an infallible operation; this function only returns a Result because writing to the underlying stream might fail and it must provide a way to propagate the fact that an error has occurred back up the stack.

Examples

use std::fmt;

struct Position {
    longitude: f32,
    latitude: f32,
}

impl fmt::Display for Position {
    fn fmt(&self, f: &mut fmt::Formatter<'_>) -> fmt::Result {
        write!(f, "({}, {})", self.longitude, self.latitude)
    }
}

assert_eq!(
    "(1.987, 2.983)",
    format!("{}", Position { longitude: 1.987, latitude: 2.983, }),
);

impl Display for NaiveDate

The Display output of the naive date d is the same as d.format("%Y-%m-%d").

The string printed can be readily parsed via the parse method on str.

Example

use chrono::NaiveDate;

assert_eq!(format!("{}", NaiveDate::from_ymd_opt(2015, 9, 5).unwrap()), "2015-09-05");
assert_eq!(format!("{}", NaiveDate::from_ymd_opt(0, 1, 1).unwrap()), "0000-01-01");
assert_eq!(format!("{}", NaiveDate::from_ymd_opt(9999, 12, 31).unwrap()), "9999-12-31");

ISO 8601 requires an explicit sign for years before 1 BCE or after 9999 CE.

assert_eq!(format!("{}", NaiveDate::from_ymd_opt(-1, 1, 1).unwrap()), "-0001-01-01");
assert_eq!(format!("{}", NaiveDate::from_ymd_opt(10000, 12, 31).unwrap()), "+10000-12-31");

impl Display for NaiveDateTime

The Display output of the naive date and time dt is the same as dt.format("%Y-%m-%d %H:%M:%S%.f").

It should be noted that, for leap seconds not on the minute boundary, it may print a representation not distinguishable from non-leap seconds. This doesn’t matter in practice, since such leap seconds never happened. (By the time of the first leap second on 1972-06-30, every time zone offset around the world has standardized to the 5-minute alignment.)

Example

use chrono::NaiveDate;

let dt = NaiveDate::from_ymd_opt(2016, 11, 15).unwrap().and_hms_opt(7, 39, 24).unwrap();
assert_eq!(format!("{}", dt), "2016-11-15 07:39:24");

Leap seconds may also be used.

let dt =
    NaiveDate::from_ymd_opt(2015, 6, 30).unwrap().and_hms_milli_opt(23, 59, 59, 1_500).unwrap();
assert_eq!(format!("{}", dt), "2015-06-30 23:59:60.500");

impl Display for NaiveTime

The Display output of the naive time t is the same as t.format("%H:%M:%S%.f").

The string printed can be readily parsed via the parse method on str.

It should be noted that, for leap seconds not on the minute boundary, it may print a representation not distinguishable from non-leap seconds. This doesn’t matter in practice, since such leap seconds never happened. (By the time of the first leap second on 1972-06-30, every time zone offset around the world has standardized to the 5-minute alignment.)

Example

use chrono::NaiveTime;

assert_eq!(format!("{}", NaiveTime::from_hms_opt(23, 56, 4).unwrap()), "23:56:04");
assert_eq!(
    format!("{}", NaiveTime::from_hms_milli_opt(23, 56, 4, 12).unwrap()),
    "23:56:04.012"
);
assert_eq!(
    format!("{}", NaiveTime::from_hms_micro_opt(23, 56, 4, 1234).unwrap()),
    "23:56:04.001234"
);
assert_eq!(
    format!("{}", NaiveTime::from_hms_nano_opt(23, 56, 4, 123456).unwrap()),
    "23:56:04.000123456"
);

Leap seconds may also be used.

assert_eq!(
    format!("{}", NaiveTime::from_hms_milli_opt(6, 59, 59, 1_500).unwrap()),
    "06:59:60.500"
);

RFC 4398, Storing Certificates in DNS, November 1987

[2.2](https://datatracker.ietf.org/doc/html/rfc4398#section-2.2).  Text Representation of CERT RRs

   The RDATA portion of a CERT RR has the type field as an unsigned
   decimal integer or as a mnemonic symbol as listed in [Section 2.1](https://datatracker.ietf.org/doc/html/rfc4398#section-2.1),
   above.

   The key tag field is represented as an unsigned decimal integer.

   The algorithm field is represented as an unsigned decimal integer or
   a mnemonic symbol as listed in [[12](https://datatracker.ietf.org/doc/html/rfc4398#ref-12)].

   The certificate/CRL portion is represented in base 64 [[16](https://datatracker.ietf.org/doc/html/rfc4398#ref-16)] and may be
   divided into any number of white-space-separated substrings, down to
   single base-64 digits, which are concatenated to obtain the full
   signature.  These substrings can span lines using the standard
   parenthesis.

   Note that the certificate/CRL portion may have internal sub-fields,
   but these do not appear in the master file representation.  For
   example, with type 254, there will be an OID size, an OID, and then
   the certificate/CRL proper.  However, only a single logical base-64
   string will appear in the text representation.

The format returned by this implementation is not stable and must not be relied upon.

By default this produces an exact, full-precision printout of the duration. For a concise, rounded printout instead, you can use the .N format specifier:

let duration = Duration::new(123456, 789011223);
println!("{duration:.3}");

For the purposes of this implementation, a day is exactly 24 hours and a minute is exactly 60 seconds.

HINFO (Host Info)

           <host>   [<ttl>] [<class>]   HINFO   <hardware>   <software>

   The HINFO record gives information about a particular host.  The data
   is two strings separated by whitespace.  The first string is a
   hardware description and the second is software.  The hardware is
   usually a manufacturer name followed by a dash and model designation.
   The software string is usually the name of the operating system.

   Official HINFO types can be found in the latest Assigned Numbers RFC,
   the latest of which is RFC-1010.  The Hardware type is called the
   Machine name and the Software type is called the System name.

   Some sample HINFO records:

           SRI-NIC.ARPA.           HINFO   DEC-2060 TOPS20
           UCBARPA.Berkeley.EDU.   HINFO   VAX-11/780 UNIX

          <name>   [<ttl>] [<class>]   MX   <preference>   <host>

  MX records specify where mail for a domain name should be delivered.
  There may be multiple MX records for a particular name.  The
  preference value specifies the order a mailer should try multiple MX
  records when delivering mail.  Zero is the highest preference.
  Multiple records for the same name may have the same preference.

  A host BAR.FOO.COM may want its mail to be delivered to the host
  PO.FOO.COM and would then use the MX record:

          BAR.FOO.COM.    MX      10      PO.FOO.COM.

  A host BAZ.FOO.COM may want its mail to be delivered to one of three
  different machines, in the following order:

          BAZ.FOO.COM.    MX      10      PO1.FOO.COM.
                          MX      20      PO2.FOO.COM.
                          MX      30      PO3.FOO.COM.

  An entire domain of hosts not connected to the Internet may want
  their mail to go through a mail gateway that knows how to deliver
  mail to them.  If they would like mail addressed to any host in the
  domain FOO.COM to go through the mail gateway they might use:

          FOO.COM.        MX       10     RELAY.CS.NET.
          *.FOO.COM.      MX       20     RELAY.CS.NET.

  Note that you can specify a wildcard in the MX record to match on
  anything in FOO.COM, but that it won't match a plain FOO.COM.

Master File Format

  The master file format follows the standard rules in RFC-1035 [1].
  Order and preference, being 16-bit unsigned integers, shall be an
  integer between 0 and 65535.  The Flags and Services and Regexp
  fields are all quoted <character-string>s.  Since the Regexp field
  can contain numerous backslashes and thus should be treated with
  care.  See Section 10 for how to correctly enter and escape the
  regular expression.

RFC 1033, DOMAIN OPERATIONS GUIDE, November 1987

SOA  (Start Of Authority)

<name>  [<ttl>]  [<class>]  SOA  <origin>  <person>  (
   <serial>
   <refresh>
   <retry>
   <expire>
   <minimum> )

The Start Of Authority record designates the start of a zone.  The
zone ends at the next SOA record.

<name> is the name of the zone.

<origin> is the name of the host on which the master zone file
resides.

<person> is a mailbox for the person responsible for the zone.  It is
formatted like a mailing address but the at-sign that normally
separates the user from the host name is replaced with a dot.

<serial> is the version number of the zone file.  It should be
incremented anytime a change is made to data in the zone.

<refresh> is how long, in seconds, a secondary name server is to
check with the primary name server to see if an update is needed.  A
good value here would be one hour (3600).

<retry> is how long, in seconds, a secondary name server is to retry
after a failure to check for a refresh.  A good value here would be
10 minutes (600).

<expire> is the upper limit, in seconds, that a secondary name server
is to use the data before it expires for lack of getting a refresh.
You want this to be rather large, and a nice value is 3600000, about
42 days.

<minimum> is the minimum number of seconds to be used for TTL values
in RRs.  A minimum of at least a day is a good value here (86400).

There should only be one SOA record per zone.  A sample SOA record
would look something like:

@   IN   SOA   SRI-NIC.ARPA.   HOSTMASTER.SRI-NIC.ARPA. (
    45         ;serial
    3600       ;refresh
    600        ;retry
    3600000    ;expire
    86400 )    ;minimum

3.2.  Presentation Format of the SSHFP RR

   The RDATA of the presentation format of the SSHFP resource record
   consists of two numbers (algorithm and fingerprint type) followed by

       host.example.  SSHFP 2 1 123456789abcdef67890123456789abcdef67890

   The use of mnemonics instead of numbers is not allowed.

impl Display for TLSA

RFC 6698, DNS-Based Authentication for TLS

2.2.  TLSA RR Presentation Format

  The presentation format of the RDATA portion (as defined in
  [RFC1035]) is as follows:

  o  The certificate usage field MUST be represented as an 8-bit
     unsigned integer.

  o  The selector field MUST be represented as an 8-bit unsigned
     integer.

  o  The matching type field MUST be represented as an 8-bit unsigned
     integer.

  o  The certificate association data field MUST be represented as a
     string of hexadecimal characters.  Whitespace is allowed within
     the string of hexadecimal characters, as described in [RFC1035].

2.3.  TLSA RR Examples

   In the following examples, the domain name is formed using the rules
   in Section 3.

   An example of a hashed (SHA-256) association of a PKIX CA
   certificate:

   _443._tcp.www.example.com. IN TLSA (
      0 0 1 d2abde240d7cd3ee6b4b28c54df034b9
            7983a1d16e8a410e4561cb106618e971 )

   An example of a hashed (SHA-512) subject public key association of a
   PKIX end entity certificate:

RFC 1033, DOMAIN OPERATIONS GUIDE, November 1987

  RESOURCE RECORDS

  Records in the zone data files are called resource records (RRs).
  They are specified in RFC-883 and RFC-973.  An RR has a standard
  format as shown:

          <name>   [<ttl>]   [<class>]   <type>   <data>

  The record is divided into fields which are separated by white space.

     <name>

        The name field defines what domain name applies to the given
        RR.  In some cases the name field can be left blank and it will
        default to the name field of the previous RR.

     <ttl>

        TTL stands for Time To Live.  It specifies how long a domain
        resolver should cache the RR before it throws it out and asks a
        domain server again.  See the section on TTL's.  If you leave
        the TTL field blank it will default to the minimum time
        specified in the SOA record (described later).

     <class>

        The class field specifies the protocol group.  If left blank it
        will default to the last class specified.

     <type>

        The type field specifies what type of data is in the RR.  See
        the section on types.

     <data>

        The data field is defined differently for each type and class
        of data.  Popular RR data formats are described later.
