Code

rama::http::proto::h3

Struct Code

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

Available on crate features http and std only.

Expand description

An HTTP/3 or QPACK error code, as carried by RESET_STREAM, STOP_SENDING, GOAWAY and the QUIC CONNECTION_CLOSE application-error space (RFC 9114 §8.1, RFC 9204 §6).

Unknown and reserved values are preserved rather than rejected: an endpoint treats an unrecognized code the same as Code::H3_NO_ERROR (RFC 9114 §8.1), and reserved (0x1f * N + 0x21) codes exist only so that endpoints do not ossify around a fixed set.

Implementations§

impl Code

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

Construct a code from its raw value.

pub const fn value(self) -> u64

The raw code value.

pub const fn is_reserved(self) -> bool

Whether this is a reserved code of the form 0x1f * N + 0x21 (RFC 9114 §8.1).

These are used to exercise requirements that unknown codes be handled gracefully; they have no other semantics.

pub const fn name(self) -> Option<&'static str>

A human-readable name for a known code, if any.

impl Code

pub const H3_NO_ERROR: Code

No error (RFC 9114 §8.1). Also used for any unrecognized error code.

pub const H3_GENERAL_PROTOCOL_ERROR: Code

Peer violated protocol requirements without a more specific code.

pub const H3_INTERNAL_ERROR: Code

Internal error.

pub const H3_STREAM_CREATION_ERROR: Code

A stream was created that could not be created.

pub const H3_CLOSED_CRITICAL_STREAM: Code

A required critical stream was closed.

pub const H3_FRAME_UNEXPECTED: Code

A frame was received on a stream where it is not permitted.

pub const H3_FRAME_ERROR: Code

A frame that fails to satisfy layout requirements.

pub const H3_EXCESSIVE_LOAD: Code

An endpoint detected that its peer is creating excessive load.

pub const H3_ID_ERROR: Code

A stream or push ID was used incorrectly.

pub const H3_SETTINGS_ERROR: Code

An endpoint detected an error in the SETTINGS frame.

pub const H3_MISSING_SETTINGS: Code

No SETTINGS frame was received at the beginning of the control stream.

pub const H3_REQUEST_REJECTED: Code

A request was rejected without processing.

pub const H3_REQUEST_CANCELLED: Code

The request or its response is cancelled.

pub const H3_REQUEST_INCOMPLETE: Code

The client’s stream terminated without a complete request.

pub const H3_MESSAGE_ERROR: Code

An HTTP message was malformed and cannot be processed.

pub const H3_CONNECT_ERROR: Code

The TCP connection established for a CONNECT request was reset or abnormally closed.

pub const H3_VERSION_FALLBACK: Code

The requested operation cannot be served over HTTP/3; peer should retry over HTTP/1.1.

pub const QPACK_DECOMPRESSION_FAILED: Code

The decoder failed to interpret an encoded field section (RFC 9204 §6).

pub const QPACK_ENCODER_STREAM_ERROR: Code

Error on the encoder stream (RFC 9204 §6).

pub const QPACK_DECODER_STREAM_ERROR: Code

Error on the decoder stream (RFC 9204 §6).
