Enum ChannelError 

#[non_exhaustive]
pub enum ChannelError {
    Timeout,
    TooLarge,
    Transport(Redacted),
}

Why a channel produced no response. Every variant means “the hook did not answer”: the adapter fails closed (SPEC-SERVER §8).

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.

Timeout

The channel gave up waiting.

TooLarge

The response exceeded max_response_bytes and its status is unknown.

Transport(Redacted)

Connection, TLS, binding or other failure. Core never prints the text.

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, __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.
