Typed dispatch-failure surface. Every variant here is CONSTRUCTED by the dispatch path — the M3 review (2026-06-12) found five declared-but-never-built variants advertising a typed API the error paths didn’t deliver; MissingMaterial (materialless nodes are clear nodes by design, so the state was unreachable) is deleted and the rest now flow through Dispatcher::dispatch_node via Display at the trait seam (the engawa trait returns DispatchError, so typed variants stringify exactly once there).

Trait Implementations

impl Debug for WgpuDispatcherError

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

Formats the value using the given formatter.

impl Display for WgpuDispatcherError

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

Formats the value using the given formatter.

impl Error for WgpuDispatcherError

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<DispatchError> for WgpuDispatcherError

fn from(source: DispatchError) -> Self

Converts to this type from the input type.
