StreamRejected

Stream open request was rejected by the peer.

Fields

code: RejectCode

The rejection code.

reason: Option<String>

Optional reason message.

SessionClosed

Session has been closed.

Disconnected

Connection to peer was lost.

CapacityExceeded(&'static str)

Capacity limit reached.

Config(ConfigError)

Configuration error.

Control(ControlError)

Control protocol error.

Codec(CodecError)

Codec error during message encoding/decoding.

Implementations

impl Error

pub fn transport<E>(error: E) -> Self

where E: Error + Send + Sync + 'static,

Creates a transport error from any error type.

pub fn protocol_violation(message: impl Into<String>) -> Self

Creates a protocol violation error.

pub const fn stream_rejected(code: RejectCode, reason: Option<String>) -> Self

Creates a stream rejected error.

Trait Implementations

impl Debug for Error

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

Formats the value using the given formatter.

impl Display for Error

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

Formats the value using the given formatter.

impl Error for Error

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<CodecError> for Error

fn from(source: CodecError) -> Self

Converts to this type from the input type.

impl From<ControlError> for Error

fn from(source: ControlError) -> Self

Converts to this type from the input type.
