Enum CallError

pub enum CallError {
    Resolve(ResolveError),
    Runtime(RuntimeError),
}

This error type is produced by calling a wasm function exported from a module.

If the module traps in some way while running, this will be the CallError::Runtime(RuntimeError) variant.

Comparing two CallErrors always evaluates to false.

Variants

Resolve(ResolveError)

An error occured resolving the functions name or types.

Runtime(RuntimeError)

A runtime error occurred during the function call.

Trait Implementations

impl Debug for CallError

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

Formats the value using the given formatter.

impl Display for CallError

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

Formats the value using the given formatter.

impl Error for CallError

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<CallError> for Error

fn from(call_err: CallError) -> Self

Converts to this type from the input type.

impl From<ResolveError> for CallError

fn from(resolve_err: ResolveError) -> Self

Converts to this type from the input type.

impl From<RuntimeError> for CallError

fn from(runtime_err: RuntimeError) -> Self

Converts to this type from the input type.

impl PartialEq for CallError

fn eq(&self, _other: &CallError) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
