Enum ChannelError 

pub enum ChannelError {
    Unreachable,
    Permanent(String),
    Transient {
        retry_after: Option<Duration>,
    },
}

Why a Channel could not deliver.

Variants

Unreachable

The account cannot be reached on this channel — its linked credential is gone. Dead-letters rather than retries: only the account can fix it, by linking again.

Permanent(String)

A permanent refusal. Dead-letters with the message as the reason: nothing about this notification will ever be accepted.

Transient

A transient failure. Retried with backoff, never before the retry_after the channel asked for, to the module’s attempt bound.

Fields

retry_after: Option<Duration>

Trait Implementations

impl Clone for ChannelError

fn clone(&self) -> Self

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for ChannelError

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

Formats the value using the given formatter.

impl Display for ChannelError

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

Formats the value using the given formatter.

impl Eq for ChannelError

impl Error for ChannelError

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 ChannelError

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

Equality operator ==.

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

Inequality operator !=.
