Enum DispatchError 

pub enum DispatchError {
    Truncated,
    UnknownKind(u16),
    Wire(WireError),
}

Top-level errors the FoldRegistry::dispatch surfaces. Distinct from WireError because the registry layer surfaces routing-shaped failures (no fold for this kind, truncated envelope) separately from per-fold codec / verification errors.

Variants

Truncated

Envelope was shorter than the 1-3 byte postcard varint the wire kind field occupies (an empty buffer, or a continuation-byte-promised followup that’s missing).

UnknownKind(u16)

No fold registered for the envelope’s kind. The dispatch layer logs + drops; the kind is surfaced so operator dashboards can pick up “publisher is on the wrong wire schema.”

Wire(WireError)

Per-fold codec / verification / apply error. Wraps the underlying WireError so the caller can pattern-match against the specific failure mode.

Trait Implementations

impl Debug for DispatchError

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

Formats the value using the given formatter.

impl Display for DispatchError

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

Formats the value using the given formatter.

impl Error for DispatchError

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<WireError> for DispatchError

fn from(source: WireError) -> Self

Converts to this type from the input type.
