An error that happened while invoking a Wasm function.

Variants

FailedWithNoError

Indicates an exceptional circumstance such as a bug in Wasmer (please file an issue!) or a hardware failure.

UnknownTrap

Indicates that a trap occurred that is not known to Wasmer.

Fields of UnknownTrap

address: usize

The address that the trap occurred at.

signal: &'static str

The name of the signal.

TrapCode

A trap that Wasmer knows about occurred.

Fields of TrapCode

code: ExceptionCode

The type of exception.

srcloc: u32

Where in the Wasm file this trap orginated from.

UnknownTrapCode

A trap occurred that Wasmer knows about but it had a trap code that we weren’t expecting or that we do not handle. This error may be backend-specific.

Fields of UnknownTrapCode

trap_code: String

The trap code we saw but did not recognize.

srcloc: u32

Where in the Wasm file this trap orginated from.

EarlyTrap

An “early trap” occurred. TODO: document this properly

Tuple Fields of EarlyTrap

0: Box<RuntimeError>

Breakpoint

Indicates that a breakpoint was hit. The inner value is dependent upon the middleware or backend being used.

Tuple Fields of Breakpoint

0: Box<RuntimeError>

Trait Implementations

impl Debug for InvokeError

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

Formats the value using the given formatter.

impl Display for InvokeError

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

Formats the value using the given formatter.

impl Error for InvokeError

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 1.42.0:

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

impl From<InvokeError> for RuntimeError

fn from(other: InvokeError) -> RuntimeError

Performs the conversion.
