Failure to build an outbound HTTP/3 SETTINGS frame.

Variants

Frame(Http3FrameBuildError)

Building the raw HTTP/3 frame envelope failed.

SettingVarInt

A SETTINGS field cannot be canonically encoded as a QUIC variable-length integer.

Fields

field: Http3FramePayloadField

Field whose value could not be encoded.

error: QuicVarIntBuildError

Underlying QUIC variable-length integer failure.

PayloadLengthOverflow

Adding a SETTINGS entry component overflowed usize.

Fields

index: usize

Index of the SETTINGS entry being accumulated.

current: usize

Accumulated payload length before the addition.

addition: usize

Component length being added.

ScratchTooShort

The caller-provided SETTINGS workspace is too short.

Fields

required: usize

Bytes required for the canonical SETTINGS payload.

available: usize

Bytes available in the caller workspace.

DuplicateSetting

The outgoing SETTINGS list contains the same identifier more than once.

Fields

id: Http3SettingId

Repeated raw setting identifier.

ProhibitedSetting

The outgoing SETTINGS list contains an HTTP/2-only reserved identifier.

Fields

id: Http3SettingId

Reserved raw setting identifier.
