Failure to construct an HTTP/2 frame in caller-provided storage.

Variants

ZeroStreamId

A frame that requires a stream was given the zero stream identifier.

ReservedStreamId

The outgoing stream identifier has its reserved high bit set.

ZeroWindowIncrement

A WINDOW_UPDATE frame was given a zero 31-bit increment.

ReservedWindowIncrement

The outgoing WINDOW_UPDATE increment has its reserved high bit set.

SettingsAckPayload

A SETTINGS ACK frame was given one or more settings.

Fields

actual: usize

Encoded payload length in bytes.

InvalidSettingValue

A SETTINGS parameter has an intrinsically invalid value.

Fields

id: Http2SettingId

Encoded setting identifier.

value: u32

Encoded setting value.

ReservedLastStreamId

The outgoing GOAWAY last-stream identifier has its reserved high bit set.

DataPaddedFlagSet

Caller-supplied DATA flags include PADDED, which is controlled by the padding argument.

HeadersPaddedFlagSet

Caller-supplied HEADERS flags include PADDED, which is controlled by the padding argument.

HeadersPriorityFlagSet

Caller-supplied HEADERS flags include PRIORITY, which is controlled by the priority argument.

PushPromisePaddedFlagSet

Caller-supplied PUSH_PROMISE flags include PADDED, which is controlled by the padding argument.

ZeroPromisedStreamId

A PUSH_PROMISE frame was given a zero promised stream identifier.

ReservedPromisedStreamId

A PUSH_PROMISE frame was given a promised stream identifier with its reserved bit set.

PayloadTooLarge

The payload exceeds the caller-provided maximum or HTTP/2’s 24-bit length field.

Fields

maximum: usize

Maximum permitted payload length.

actual: usize

Supplied payload length.

BufferTooShort

The caller buffer cannot contain the complete frame.

Fields

required: usize

Required bytes.

available: usize

Available bytes.
