Enum Version 

pub enum Version {
    Http10,
    Http11,
    Http2,
    Http3,
}

The HTTP version from the request line.

Only the HTTP/1.x family is parsed by this engine; HTTP/2 and HTTP/3 use entirely different framing and are out of scope.

Variants

Http10

HTTP/1.0 — connections close by default unless Connection: keep-alive.

Http11

HTTP/1.1 — connections persist by default unless Connection: close.

Http2

HTTP/2 (RFC 9113) — binary, multiplexed; framing replaces the textual request line. Carried on a connection negotiated via ALPN.

Http3

HTTP/3 (RFC 9114) — like HTTP/2 but carried over QUIC streams.

Implementations

impl Version

pub fn parse(token: &str) -> Option<Version>

Parse the HTTP/x.y token from a request line.

pub fn as_str(self) -> &'static str

The wire representation, e.g. "HTTP/1.1".

pub fn default_keep_alive(self) -> bool

Whether persistent connections are the default for this version.

Trait Implementations

impl Clone for Version

fn clone(&self) -> Version

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for Version

impl Debug for Version

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

Formats the value using the given formatter.

impl Display for Version

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

Formats the value using the given formatter.

impl Eq for Version

impl From<Version> for Version

fn from(v: Version) -> Self

Converts to this type from the input type.

impl From<Version> for Version

fn from(v: Version) -> Self

Converts to this type from the input type.

impl PartialEq for Version

fn eq(&self, other: &Version) -> 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.
