Enum InvokeError

pub enum InvokeError<E>
where
    E: SelfError,
{
    SelfError(E),
    Downstream(RuntimeError),
}

This enum is to help with designing intuitive error abstractions. Each engine module can have its own SelfError, but can also wrap arbitrary downstream errors. Ultimately these errors get flattened out to a RuntimeError anyway.

Variants

SelfError(E)

Downstream(RuntimeError)

Implementations

impl<E> InvokeError<E>

where E: SelfError,

pub fn error(error: E) -> InvokeError<E>

pub fn downstream(runtime_error: RuntimeError) -> InvokeError<E>

Trait Implementations

impl<E> Clone for InvokeError<E>

where E: Clone + SelfError,

fn clone(&self) -> InvokeError<E>

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl<E> Debug for InvokeError<E>

where E: Debug + SelfError,

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

Formats the value using the given formatter.

impl Display for InvokeError<WasmRuntimeError>

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

Formats the value using the given formatter.

impl Error for InvokeError<WasmRuntimeError>

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
