Enum H2Error 

pub enum H2Error {
    Protocol(H2ErrorCode),
    Io(Error),
}

An error that may occur during HTTP/2 stream or connection processing.

When the error is Protocol, the contained H2ErrorCode should be communicated to the peer via GOAWAY (for connection-level errors) or RST_STREAM (for stream-level errors); the distinction is contextual. Io errors indicate an unrecoverable transport failure.

Variants

Protocol(H2ErrorCode)

An HTTP/2 protocol error; the code should be signalled to the peer.

Io(Error)

An unrecoverable I/O error encountered at the network layer.

Trait Implementations

impl Debug for H2Error

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

Formats the value using the given formatter.

impl Display for H2Error

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

Formats the value using the given formatter.

impl Error for H2Error

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 From<Error> for H2Error

fn from(source: Error) -> Self
