Error type for lane operations.

Variants

NotInitialized

The lane has not been initialized yet.

InvalidContext

The execution context passed to the lane has the wrong type.

Fields

expected: &'static str

What the lane expected.

received: String

Description of what was received.

LockPoisoned

A RwLock / Mutex was poisoned by a prior panic.

Fields

context: &'static str

Which lock — used in the error message for diagnostics.

MissingResource

A required GPU resource (pipeline, buffer, texture, sampler) was not present in the registry the lane consulted.

Fields

kind: &'static str

What kind of resource (e.g. "pipeline", "buffer").

key: String

Human-readable key the lane looked up.

MissingAsset

A required asset was not present in the registry / cache.

Fields

kind: &'static str

Asset kind ("mesh", "texture", …).

id: String

Stringified asset id (UUID, name, …).

ExecutionFailed(Box<dyn Error + Send + Sync>)

A domain-specific error occurred during execution.

InitializationFailed(Box<dyn Error + Send + Sync>)

A domain-specific error occurred during initialization.

Implementations

impl LaneError

pub fn missing(type_name: &'static str) -> Self

Convenience constructor for a missing context entry.

pub fn lock_poisoned(context: &'static str) -> Self

Convenience constructor for a poisoned lock.

pub fn missing_resource(kind: &'static str, key: impl Into<String>) -> Self

Convenience constructor for a missing resource.

pub fn missing_asset(kind: &'static str, id: impl Display) -> Self

Convenience constructor for a missing asset.

Trait Implementations

impl Debug for LaneError

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

Formats the value using the given formatter.

impl Display for LaneError

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

Formats the value using the given formatter.

impl Error for LaneError

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.
