Enum TransferEncodingDirective 

pub enum TransferEncodingDirective {

    Deflate,
    Gzip,

}

Available on crate feature http only.

Directive for the TransferEncoding header.

Variants

Compress

A format using the Lempel-Ziv-Welch (LZW) algorithm.

The value name was taken from the UNIX compress program, which implemented this algorithm. Like the compress program, which has disappeared from most UNIX distributions, this content-encoding is used by almost no browsers today, partly because of a patent issue (which expired in 2003).

Deflate

Using the zlib structure (defined in RFC 1950) with the deflate compression algorithm (defined in RFC 1951).

Gzip

A format using the Lempel-Ziv coding (LZ77), with a 32-bit CRC. This is the original format of the UNIX gzip program.

The HTTP/1.1 standard also recommends that the servers supporting this content-encoding should recognize x-gzip as an alias, for compatibility purposes.

Chunked

Data is sent in a series of chunks.

Content can be sent in streams of unknown size to be transferred as a sequence of length-delimited buffers, so the sender can keep a connection open, and let the recipient know when it has received the entire message. The Content-Length header must be omitted, and at the beginning of each chunk, a string of hex digits indicate the size of the chunk-data in octets, followed by \r\n and then the chunk itself, followed by another \r\n. The terminating chunk is a zero-length chunk.

Implementations

impl TransferEncodingDirective

pub fn as_str(&self) -> &str

pub fn as_smol_str(&self) -> SmolStr

impl TransferEncodingDirective

pub fn strict_parse(s: &str) -> Option<TransferEncodingDirective>

Same as FromStr or From<&str> but returning None for unknown values

Trait Implementations

impl Clone for TransferEncodingDirective

fn clone(&self) -> TransferEncodingDirective

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for TransferEncodingDirective

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for TransferEncodingDirective

fn deserialize<D>( deserializer: D, ) -> Result<TransferEncodingDirective, <D as Deserializer<'de>>::Error>

where D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Display for TransferEncodingDirective

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

Formats the value using the given formatter.

impl<'a> From<&'a str> for TransferEncodingDirective

fn from(s: &'a str) -> TransferEncodingDirective

Converts to this type from the input type.

impl From<String> for TransferEncodingDirective

fn from(s: String) -> TransferEncodingDirective

Converts to this type from the input type.

impl FromStr for TransferEncodingDirective

type Err = Infallible

The associated error which can be returned from parsing.

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

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

impl Hash for TransferEncodingDirective

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 for TransferEncodingDirective

fn eq(&self, other: &TransferEncodingDirective) -> 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 Serialize for TransferEncodingDirective

fn serialize<S>( &self, serializer: S, ) -> Result<<S as Serializer>::Ok, <S as Serializer>::Error>

where S: Serializer,

Serialize this value into the given Serde serializer.

impl Eq for TransferEncodingDirective
