}

Errors that can occur when dispatching a function call to plugins.

Returned inside a cardinality wrapper from Binding::dispatch when a function call fails at runtime.

Variants

LockRejected

Failed to acquire lock on plugin instance (another call is in progress).

InvalidInterfacePath(String)

The specified interface path doesn’t match any known interface.

InvalidFunction(String)

The specified function doesn’t exist on the interface.

MissingResponse

Function was expected to return a value but didn’t.

RuntimeException(Error)

The WASM function threw an exception during execution.

InvalidArgumentList

The provided arguments don’t match the function signature.

UnsupportedType(String)

Async types (Future, Stream, ErrorContext) are not yet supported for cross-plugin transfer.

ResourceCreationError(ResourceCreationError)

Failed to create a resource handle for cross-plugin transfer.

ResourceReceiveError(ResourceReceiveError)

Failed to receive a resource handle from another plugin.

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<DispatchError> for Val

fn from(error: DispatchError) -> Val

Converts to this type from the input type.

impl From<ResourceCreationError> for DispatchError

fn from(source: ResourceCreationError) -> Self

Converts to this type from the input type.

impl From<ResourceReceiveError> for DispatchError

fn from(source: ResourceReceiveError) -> Self

Converts to this type from the input type.
