Variants

Incomplete

Fewer bytes than a fixed prefix or declared frame payload were supplied.

Fields

required: usize

Required bytes.

available: usize

Available bytes.

ClientPrefaceMismatch

A byte differs from the required client-preface byte.

Fields

offset: usize

Offset of the mismatched byte.

expected: u8

Required byte.

actual: u8

Supplied byte.

PayloadTooLarge

A declared frame payload exceeds the caller-provided maximum.

Fields

maximum: usize

Caller-provided maximum payload length.

actual: usize

Declared payload length.

WrongFrameType

A typed frame view was requested for a different raw frame type.

Fields

expected: Http2FrameType

Required frame type.

actual: Http2FrameType

Actual frame type.

ZeroStreamId

A frame that requires a stream has a zero 31-bit stream identifier.

ExpectedZeroStreamId

A frame that requires the connection stream has a nonzero 31-bit stream identifier.

FrameSizeMismatch

A fixed-layout frame has an unexpected payload length.

Fields

expected: usize

Required payload length.

actual: usize

Actual payload length.

ZeroWindowIncrement

A WINDOW_UPDATE frame has a zero 31-bit increment.

SettingsPayloadLength

A SETTINGS payload does not contain a whole number of six-byte parameters.

Fields

actual: usize

Actual payload length.

SettingsAckPayload

A SETTINGS frame with ACK set has a nonempty payload.

Fields

actual: usize

Actual payload length.

InvalidSettingValue

A SETTINGS parameter has an intrinsically invalid value.

Fields

id: Http2SettingId

Encoded setting identifier.

value: u32

Encoded setting value.

ZeroPromisedStreamId

A PUSH_PROMISE frame has a zero 31-bit promised stream identifier.

InvalidPadding

A PADDED frame has no pad-length byte or declares too much padding.

Fields

padding_length: u8

Encoded padding length, or zero when the pad-length byte is absent.

payload_length: usize

Total payload length.

MalformedPayload

A required intrinsic payload section is truncated.

Fields

required: usize

Required bytes in the section.

available: usize

Available bytes in the section.
