Struct Code 

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

An HTTP/3 “application error code” (RFC 9114 §8.1).

A newtype rather than an enum: the registry is open, and a peer may close a connection with a code this server has never heard of, which still has to be logged rather than lost.

Implementations

impl Code

pub const fn value(self) -> u64

The code as it appears on the wire.

pub const fn new(value: u64) -> Self

Wraps a raw code, including ones outside the registry.

impl Code

pub const H3_DATAGRAM_ERROR: Code

A datagram or capsule could not be parsed (RFC 9297 §5.2).

pub const H3_NO_ERROR: Code

No error: a close with nothing to report (RFC 9114 §8.1).

pub const H3_GENERAL_PROTOCOL_ERROR: Code

A protocol violation with no more specific code (RFC 9114 §8.1).

pub const H3_INTERNAL_ERROR: Code

A fault inside this HTTP/3 layer rather than in the peer’s message.

pub const H3_STREAM_CREATION_ERROR: Code

The peer created a stream this endpoint will not accept (RFC 9114 §6.2).

pub const H3_CLOSED_CRITICAL_STREAM: Code

A stream the connection depends on was closed or reset (RFC 9114 §6.2.1).

pub const H3_FRAME_UNEXPECTED: Code

A frame arrived where it is not allowed (RFC 9114 §7.2).

pub const H3_FRAME_ERROR: Code

A frame’s layout or size is invalid (RFC 9114 §7.1).

pub const H3_EXCESSIVE_LOAD: Code

The peer is behaving in a way that might generate excessive load.

pub const H3_ID_ERROR: Code

A stream or push id was used incorrectly (RFC 9114 §5.2).

pub const H3_SETTINGS_ERROR: Code

A SETTINGS payload broke one of RFC 9114 §7.2.4’s rules.

pub const H3_MISSING_SETTINGS: Code

The control stream did not begin with SETTINGS (RFC 9114 §6.2.1).

pub const H3_REQUEST_REJECTED: Code

The request was rejected without being processed (RFC 9114 §5.2).

pub const H3_REQUEST_CANCELLED: Code

The request or its response is cancelled (RFC 9114 §8.1).

pub const H3_REQUEST_INCOMPLETE: Code

The request stream ended without a fully formed request (RFC 9114 §4.1).

pub const H3_MESSAGE_ERROR: Code

An HTTP message was malformed (RFC 9114 §4.1.2).

pub const H3_CONNECT_ERROR: Code

The connection made for a CONNECT request failed (RFC 9114 §4.4).

pub const H3_VERSION_FALLBACK: Code

The request cannot be served over HTTP/3 (RFC 9114 §8.1).

pub const QPACK_DECOMPRESSION_FAILED: Code

An encoded field section could not be decoded (RFC 9204 §6).

pub const QPACK_ENCODER_STREAM_ERROR: Code

An encoder-stream instruction could not be interpreted (RFC 9204 §6).

pub const QPACK_DECODER_STREAM_ERROR: Code

A decoder-stream instruction could not be interpreted (RFC 9204 §6).

Trait Implementations

impl Clone for Code

fn clone(&self) -> Code

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for Code

impl Debug for Code

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

The same text as Display.

Log fields recorded with tracing’s ? sigil go through Debug, and a code is worth just as much there as behind %.

impl Display for Code

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

Formats the value using the given formatter.

impl Eq for Code

impl Hash for Code

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

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 Code

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