}

Public session construction, negotiation, or control failure.

Variants

BackendUnavailable

The selected native target adapter is not composed yet.

InvalidInput

Local command, environment, payload, or option input is invalid.

DeadlineExpired

The one caller-derived absolute deadline expired.

PeerDisconnected

The authenticated control endpoint closed before the operation completed.

IdentityMismatch

Kernel-authenticated process or executable identity did not match.

MalformedPeer

The peer supplied malformed or noncanonical framing.

Ambiguous

Local I/O completed at the deadline boundary with unknowable peer state.

NegotiationFailed

HELLO or challenged decision validation failed.

NativeNegotiation(NegotiationError)

Local native capability discovery or limit negotiation failed.

Control(ControlError)

Application-control sequencing or bounds validation failed.

Batch(BatchError)

Portable batch construction or committed-set validation failed.

ActiveLimit

Current active region or byte capacity cannot admit the whole batch.

PeerPreparationFailed

The peer reported a bounded local native-preparation failure before capability transfer.

ActivationFailed

Native mapping activation failed atomically without exposing a partial set.

Poisoned

Native negotiation transport was already terminally poisoned.

Native

A bounded native operation failed without a more specific safe category.

Trait Implementations

impl Clone for SessionError

fn clone(&self) -> SessionError

impl Eq for SessionError

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 PartialEq for SessionError

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

Equality operator ==.

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

Inequality operator !=.
