}

HTTP/2-layer error.

Variants

ShortFrameHeader

Frame header too short (< 9 bytes).

ShortPayload

Payload too short for the frame type.

FrameTooLarge

Frame length exceeds MAX_FRAME_SIZE.

Fields

got: u32

Received length.

max: u32

Current max frame size.

UnknownFrameType(u8)

Unknown/reserved frame type (Spec §4.1: SHOULD ignore).

BadPreface

Wrong connection preface.

InvalidState

Stream state does not allow this frame type.

StreamIdZero

Stream id 0 where stream != 0 is required.

StreamIdNonZero

Stream id != 0 where stream == 0 is required (e.g. SETTINGS).

FlowControlExceeded

Flow-control window underrun.

Protocol(ErrorCode)

Generic protocol error with code.

Trait Implementations

impl Clone for Http2Error

fn clone(&self) -> Http2Error

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Http2Error

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

Formats the value using the given formatter.

impl Display for Http2Error

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

Formats the value using the given formatter.

impl Eq for Http2Error

impl Error for Http2Error

Available on crate feature std only.

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 Http2Error

fn eq(&self, other: &Http2Error) -> bool

Tests for self and other values to be equal, and is used by ==.

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

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
