Enum ChannelError 

#[non_exhaustive]
pub enum ChannelError {
    ConnectionFailed(String),
    AuthFailed(String),
    SendFailed(String),
    ReceiveFailed(String),
    NotConnected,
    NotFound(String),
    Other(String),
}

Channel-specific error type.

Used by channel implementations (Telegram, Slack, Discord, etc.) to report failures in connecting, authenticating, or exchanging messages.

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.

ConnectionFailed(String)

Failed to establish a connection to the channel backend.

AuthFailed(String)

Authentication / authorization was rejected.

SendFailed(String)

Sending a message failed.

ReceiveFailed(String)

Receiving a message failed.

NotConnected

The channel is not currently connected.

NotFound(String)

The requested channel was not found.

Other(String)

Catch-all for errors that do not fit other variants.

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>)

🔬This is a nightly-only experimental API. (error_generic_member_access)

Provides type-based access to context intended for error reports.
