Enum CallError 

pub enum CallError {
    Bound,
    Capacity,
    Invalid,
    Correlation,
    PeerGone,
    Cancelled,
    Deadline,
    Unavailable,
    NoServer,
    GrantRefused,
}

A named crossing refusal; no request or credential bytes enter its text.

Variants

Bound

The complete call cannot fit its configured bound or the Noise ceiling.

Capacity

No additional call is admitted until an existing reservation settles.

Invalid

The call envelope is malformed or has unexpected framing.

Correlation

A reply did not match this exact call and subject.

PeerGone

The keyed peer disappeared before its answer.

Cancelled

The local caller cancelled this exact pending operation.

Deadline

The caller’s already configured pending-reply deadline elapsed.

Unavailable

State was poisoned or a response delivery could not be completed.

NoServer

No live server on either end advertises this subject.

GrantRefused

A machine no longer holds its crossing right when the answer is released.

impl Eq for CallError

impl Error for CallError

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 CallError

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

Equality operator ==.

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

Inequality operator !=.
