Enum ErrorCode 

pub enum ErrorCode {
    NoError = 0,
    ProtocolError = 1,
    InternalError = 2,
    FlowControlError = 3,
    SettingsTimeout = 4,
    StreamClosed = 5,
    FrameSizeError = 6,

}

The enum represents an error code that are used in RST_STREAM and GOAWAY frames. These are defined in Section 7 of the HTTP/2 spec.

Variants

NoError = 0

The associated condition is not a result of an error. For example, a GOAWAY might include this code to indicate graceful shutdown of a connection.

ProtocolError = 1

The endpoint detected an unspecific protocol error. This error is for use when a more specific error code is not available.

InternalError = 2

The endpoint encountered an unexpected internal error.

FlowControlError = 3

The endpoint detected that its peer violated the flow-control protocol.

SettingsTimeout = 4

The endpoint sent a SETTINGS frame but did not receive a response in a timely manner. See Section 6.5.3 (“Settings Synchronization”).

StreamClosed = 5

The endpoint received a frame after a stream was half-closed.

FrameSizeError = 6

The endpoint received a frame with an invalid size.

RefusedStream = 7

The endpoint refused the stream prior to performing any application processing (see Section 8.1.4 for details).

Cancel = 8

Used by the endpoint to indicate that the stream is no longer needed.

CompressionError = 9

The endpoint is unable to maintain the header compression context for the connection.

ConnectError = 10

The connection established in response to a CONNECT request (Section 8.3) was reset or abnormally closed.

EnhanceYourCalm = 11

The endpoint detected that its peer is exhibiting a behavior that might be generating excessive load.

InadequateSecurity = 12

The underlying transport has properties that do not meet minimum security requirements (see Section 9.2).

Http11Required = 13

The endpoint requires that HTTP/1.1 be used instead of HTTP/2.

Trait Implementations

impl AsRef<str> for ErrorCode

fn as_ref(&self) -> &str

Converts this type into a shared reference of the (usually inferred) input type.

impl Clone for ErrorCode

fn clone(&self) -> ErrorCode

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ErrorCode

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

Formats the value using the given formatter.

impl From<u32> for ErrorCode

fn from(code: u32) -> ErrorCode

Converts the given u32 number to the appropriate ErrorCode variant.

impl Into<u32> for ErrorCode

fn into(self) -> u32

Converts this type into the (usually inferred) input type.

impl PartialEq for ErrorCode

fn eq(&self, other: &ErrorCode) -> 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.

impl Copy for ErrorCode

impl Eq for ErrorCode

impl StructuralPartialEq for ErrorCode
