Enum wasmer_runtime::error::RuntimeError

pub enum RuntimeError {
    Trap {
        msg: Box<str>,
    },
    Error {
        data: Box<dyn Any + 'static + Send>,
    },
}

This is the error type returned when calling a WebAssembly function.

The main way to do this is Instance.call.

Comparing two RuntimeErrors always evaluates to false.

Trait Implementations

impl Debug for RuntimeError

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

Formats the value using the given formatter.

impl Display for RuntimeError

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

Formats the value using the given formatter.

impl Error for RuntimeError

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<RuntimeError> for CallError

fn from(runtime_err: RuntimeError) -> CallError

Performs the conversion.

impl From<RuntimeError> for Error

fn from(runtime_err: RuntimeError) -> Error

Performs the conversion.

impl PartialEq<RuntimeError> for RuntimeError

fn eq(&self, _other: &RuntimeError) -> 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 !=.
