    InvalidInterface(String),
    InvalidFunction(String),
    MissingResponse,

}

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

Returned inside the Socket from PluginTreeHead::dispatch when a function call fails at runtime.

Variants

Deadlock

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

WitParserError(I::Error)

Failed to parse interface metadata during dispatch.

InvalidInterface(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<I: Debug + InterfaceData> Debug for DispatchError<I>

where I::Error: Debug,

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

Formats the value using the given formatter.

impl<I: InterfaceData> Display for DispatchError<I>

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

Formats the value using the given formatter.

impl<I: InterfaceData> Error for DispatchError<I>

where Self: Debug + Display,

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<I: InterfaceData> From<DispatchError<I>> for Val

fn from(error: DispatchError<I>) -> Val

Converts to this type from the input type.
