Struct PrintableString

pub struct PrintableString(/* private fields */);

ASN.1 PrintableString type.

Supports a subset of the ASCII printable characters (described below).

For the full ASCII character set, use Ia5String.

Examples

You can create a PrintableString from a literal string with PrintableString::try_from:

use rcgen::string::PrintableString;
let hello = PrintableString::try_from("hello").unwrap();

Supported characters

PrintableString is a subset of the ASCII printable characters. For instance, '@' is a printable character as per ASCII but can’t be part of ASN.1’s PrintableString.

The following ASCII characters/ranges are supported:

• A..Z
• a..z
• 0..9
• “ ” (i.e. space)
• \
• (
• )
• +
• ,
• -
• .
• /
• :
• =
• ?

Implementations

impl PrintableString

pub fn as_str(&self) -> &str

Extracts a string slice containing the entire PrintableString.

Trait Implementations

impl AsRef<str> for PrintableString

fn as_ref(&self) -> &str

Converts this type into a shared reference of the (usually inferred) input type.

impl Clone for PrintableString

fn clone(&self) -> PrintableString

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for PrintableString

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

Formats the value using the given formatter.

impl Display for PrintableString

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

Formats the value using the given formatter.

impl FromStr for PrintableString

type Err = Error

The associated error which can be returned from parsing.

fn from_str( s: &str, ) -> Result<PrintableString, <PrintableString as FromStr>::Err>

Parses a string s to return a value of this type.

impl Hash for PrintableString

fn hash<__H>(&self, state: &mut __H)

where __H: Hasher,

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl PartialEq<&String> for PrintableString

fn eq(&self, other: &&String) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl PartialEq<&str> for PrintableString

fn eq(&self, other: &&str) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl PartialEq<String> for PrintableString

fn eq(&self, other: &String) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl PartialEq<str> for PrintableString

fn eq(&self, other: &str) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl PartialEq for PrintableString

fn eq(&self, other: &PrintableString) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl TryFrom<&str> for PrintableString

fn try_from(input: &str) -> Result<PrintableString, Error>

Converts a &str to a PrintableString.

Any character not in the PrintableString charset will be rejected. See PrintableString documentation for more information.

The result is allocated on the heap.

type Error = Error

The type returned in the event of a conversion error.

impl TryFrom<String> for PrintableString

fn try_from( value: String, ) -> Result<PrintableString, <PrintableString as TryFrom<String>>::Error>

Converts a String into a PrintableString

Any character not in the PrintableString charset will be rejected. See PrintableString documentation for more information.

This conversion does not allocate or copy memory.

type Error = Error

The type returned in the event of a conversion error.
