HTTP/3 errors.

Variants

UnexpectedEof

Input buffer ended unexpectedly.

InvalidFrame(&'static str)

Malformed frame.

FrameTooLarge

Frame payload exceeds maximum allowed size.

Fields

payload_size: usize

Actual decoded payload size.

max_size: usize

Configured maximum payload size.

DuplicateSetting(u64)

Duplicate setting key.

InvalidSettingValue(u64)

Invalid setting value.

ControlProtocol(&'static str)

Control stream protocol violation.

StreamProtocol(&'static str)

Unidirectional stream protocol violation.

QpackPolicy(&'static str)

QPACK policy mismatch for this connection.

InvalidRequestPseudoHeader(&'static str)

Invalid request pseudo headers.

InvalidResponsePseudoHeader(&'static str)

Invalid response pseudo headers.

ConcurrentStreamLimitExceeded

New request stream rejected because peer-advertised concurrency cap is full.

Per RFC 9114 §5.1.2, an HTTP/3 endpoint MUST respect the QUIC initial_max_streams_bidi / MAX_STREAMS limits. The local state machine returns this error when a frame arrives for a previously-unseen request-stream id while active_request_stream_count >= max.

Fields

active: u64

The number of currently active streams.

limit: u64

The maximum allowed streams.

Trait Implementations

impl Clone for H3NativeError

fn clone(&self) -> H3NativeError

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for H3NativeError

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

Formats the value using the given formatter.

impl Display for H3NativeError

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

Formats the value using the given formatter.

impl Eq for H3NativeError

impl Error for H3NativeError

fn source(&self) -> Option<&(dyn Error + 'static)>

Returns the lower-level source of this error, if any.

fn description(&self) -> &str

👎Deprecated since 1.42.0:

use the Display impl or to_string()

fn cause(&self) -> Option<&dyn Error>

👎Deprecated since 1.33.0:

replaced by Error::source, which can support downcasting

fn provide<'a>(&'a self, request: &mut Request<'a>)

🔬This is a nightly-only experimental API. (error_generic_member_access)

Provides type-based access to context intended for error reports.

impl PartialEq for H3NativeError

fn eq(&self, other: &H3NativeError) -> bool

Equality operator ==.

fn ne(&self, other: &Rhs) -> bool

Inequality operator !=.
