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.

ABNF

Content-Length = 1*DIGIT

Trait Implementations

impl Clone for ContentLength

fn clone(&self) -> ContentLength

Returns a copy 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<(), Error>

Formats the value using the given formatter.

impl DerefMut for ContentLength

fn deref_mut(&mut self) -> &mut u64

Mutably dereferences the value.

impl Display for ContentLength

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

Formats the value using the given formatter.

impl Header for ContentLength

fn header_name() -> &'static str

Returns the name of the header field this belongs to.

fn parse_header(raw: &[Vec<u8>]) -> Result<ContentLength, Error>

Parse a header from a raw stream of bytes.

impl HeaderFormat for ContentLength

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

Format a header to be output into a TcpStream.

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 Deref for ContentLength

type Target = u64

The resulting type after dereferencing.

fn deref(&self) -> &u64

Dereferences the value.

impl Copy for ContentLength

impl StructuralPartialEq for ContentLength
