Enum SessionError 

#[non_exhaustive]
pub enum SessionError<E> {
    Codec(E),
    Cancelled(StopReason),
    Finished,
    Protocol(ProtocolViolation),
    Unsupported(UnsupportedMedia),
    Limit(MediaLimitExceeded),
}

Every session error is terminal for the session except Codec errors a backend documents as retryable validation.

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.

Codec(E)

The codec or container implementation failed (malformed input, backend error).

Cancelled(StopReason)

The pulse tripped.

Finished

Called again after a terminal error.

Protocol(ProtocolViolation)

The protocol was broken.

Unsupported(UnsupportedMedia)

A valid request this implementation does not support.

Limit(MediaLimitExceeded)

A structural limit was exceeded.

Implementations

impl<E> SessionError<E>

pub fn map_codec<F>(self, f: impl FnOnce(E) -> F) -> SessionError<F>

Convert the implementation error, keeping every other variant.

Trait Implementations

impl<E: Debug> Debug for SessionError<E>

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

Formats the value using the given formatter.

impl<E: Display> Display for SessionError<E>

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

Formats the value using the given formatter.

impl<E: Error + 'static> Error for SessionError<E>

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<E> From<StopReason> for SessionError<E>

fn from(r: StopReason) -> Self

Converts to this type from the input type.
