Enum ChannelError 

#[non_exhaustive]
pub enum ChannelError {
    Unsupported(&'static str),
    Auth(String),
    RateLimited {
        retry_after: Option<Duration>,
    },
    Transient(BoxError),
    Failed(BoxError),
}

An error from a channel adapter.

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

Unsupported(&'static str)

The platform does not support the operation (see ChannelCaps).

Auth(String)

Credentials were rejected. The channel stops; the operator must fix the configuration.

RateLimited

The platform asked to slow down.

Fields

retry_after: Option<Duration>

How long to wait, when the platform says.

Transient(BoxError)

A temporary failure; retrying later may succeed.

Failed(BoxError)

A permanent failure for this request.

Implementations

impl ChannelError

pub fn is_retryable(&self) -> bool

Whether retrying the same request later may succeed.

Trait Implementations

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, __formatter: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

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>)
