Enum SessionError 

pub enum SessionError {
    UnknownPeer(String),
    PeerGone(String),
    PeerOffline(String),
    ConnectFailed(String),
    SendFailed(String),
    ReconnectBackoff {
        retry_after: Duration,
    },
    Transport(TransportError),
}

Errors from Layer 5 session operations.

Variants

UnknownPeer(String)

The specified peer is not known to the registry.

PeerGone(String)

A peer-ref selector referenced a departed or superseded registry entry generation (RFC 022 I5) — the handle it came from is stale.

PeerOffline(String)

The specified peer is offline (Layer 3 reports not online).

ConnectFailed(String)

Failed to establish a transport connection.

SendFailed(String)

Failed to send data on a transport connection.

ReconnectBackoff

Reconnect backoff is active — wait before retrying.

Fields

retry_after: Duration

How long the caller must wait before retrying.

Transport(TransportError)

A transport layer error.

Trait Implementations

impl Debug for SessionError

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

Formats the value using the given formatter.

impl Display for SessionError

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

Formats the value using the given formatter.

impl Error for SessionError

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<SessionError> for NodeError

fn from(source: SessionError) -> Self

Converts to this type from the input type.

impl From<TransportError> for SessionError

fn from(source: TransportError) -> Self

Converts to this type from the input type.
