Enum wasmer_runtime::error::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<(), Error>

Formats the value using the given formatter.

impl Display for CallError

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

Formats the value using the given formatter.

impl Error for CallError

fn source(&self) -> Option<&(dyn Error + 'static)>

The lower-level source of this error, if any.

fn backtrace(&self) -> Option<&Backtrace>

🔬 This is a nightly-only experimental API. (backtrace)

Returns a stack backtrace, if available, of where this error occurred.

fn description(&self) -> &str

Deprecated since 1.41.0:

use the Display impl or to_string()

if let Err(e) = "xc".parse::<u32>() { // Print e itself, no need for description(). eprintln!("Error: {}", e); }

fn cause(&self) -> Option<&dyn Error>

Deprecated since 1.33.0:

replaced by Error::source, which can support downcasting

impl From<CallError> for Error

fn from(call_err: CallError) -> Error

Performs the conversion.

impl From<ResolveError> for CallError

fn from(resolve_err: ResolveError) -> CallError

Performs the conversion.

impl From<RuntimeError> for CallError

impl PartialEq<CallError> for CallError

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

This method tests for self and other values to be equal, and is used by ==.

#[must_use] fn ne(&self, other: &Rhs) -> bool

This method tests for !=.
