Struct ContentLength 

pub struct ContentLength(pub u64);

Content-Length header, defined in RFC7230

When a message does not have a Transfer-Encoding header field, a Content-Length header field can provide the anticipated size, as a decimal number of octets, for a potential payload body. For messages that do include a payload body, the Content-Length field-value provides the framing information necessary for determining where the body (and message) ends. For messages that do not include a payload body, the Content-Length indicates the size of the selected representation.

Note that setting this header will remove any previously set Transfer-Encoding header, in accordance with RFC7230:

A sender MUST NOT send a Content-Length header field in any message that contains a Transfer-Encoding header field.

ABNF

Content-Length = 1*DIGIT

Trait Implementations

impl Clone for ContentLength

fn clone(&self) -> ContentLength

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ContentLength

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

Formats the value using the given formatter.

impl Header for ContentLength

fn name() -> &'static HeaderName

The name of this header.

fn decode<'i, I: Iterator<Item = &'i HeaderValue>>( values: &mut I, ) -> Result<Self, Error>

Decode this type from an iterator of HeaderValues.

fn encode<E: Extend<HeaderValue>>(&self, values: &mut E)

Encode this type to a HeaderMap.

impl PartialEq for ContentLength

fn eq(&self, other: &ContentLength) -> 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 Copy for ContentLength

impl StructuralPartialEq for ContentLength

Layout

Note: Most layout information is completely unstable and may even differ between compilations. The only exception is types with certain repr(...) attributes. Please see the Rust Reference's “Type Layout” chapter for details on type layout guarantees.
