Enum TransportError 

pub enum TransportError {
    Io(String),
    Timeout,
    Internal(String),
}

Coarse shape of a callback-transport failure.

A real callback transport (HTTP, IPC, in-process bridge) surfaces errors at varying granularity. The mapper consumes this enum so the trait is portable across transports and so the retry-class derivation has a stable input vocabulary.

Variants

Io(String)

Network or pipe-level failure: connection refused, broken pipe, peer reset.

Timeout

The remote did not respond within the configured deadline.

Internal(String)

A non-IO crash inside the transport itself (serialization panic, internal bug). Distinct from Io because the retry class differs (InternalError -> RetryAfterReread).

Trait Implementations

impl Clone for TransportError

fn clone(&self) -> TransportError

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for TransportError

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

Formats the value using the given formatter.

impl Display for TransportError

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

Formats the value using the given formatter.

impl Error for TransportError

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 From<&TransportError> for FailureClass

fn from(err: &TransportError) -> Self

Converts to this type from the input type.

impl PartialEq for TransportError

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

Tests for self and other values to be equal, and is used by ==.

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

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
