pub struct RuntimeError { /* private fields */ }
Expand description

A struct representing an aborted instruction execution, with a message indicating the cause.

Implementations§

source§

impl RuntimeError

source

pub fn new<I: Into<String>>(message: I) -> Self

Creates a new generic RuntimeError with the given message.

Example
let trap = wasmer_compiler::RuntimeError::new("unexpected error");
assert_eq!("unexpected error", trap.message());
source

pub fn from_trap(trap: Trap) -> Self

Create a new RuntimeError from a Trap.

source

pub fn user(error: Box<dyn Error + Send + Sync>) -> Self

Creates a custom user Error.

This error object can be passed through Wasm frames and later retrieved using the downcast method.

source

pub fn message(&self) -> String

Returns a reference the message stored in Trap.

source

pub fn trace(&self) -> &[FrameInfo]

Returns a list of function frames in WebAssembly code that led to this trap happening.

source

pub fn downcast<T: Error + 'static>(self) -> Result<T, Self>

Attempts to downcast the RuntimeError to a concrete type.

source

pub fn downcast_ref<T: Error + 'static>(&self) -> Option<&T>

Attempts to downcast the RuntimeError to a concrete type.

source

pub fn to_trap(self) -> Option<TrapCode>

Returns trap code, if it’s a Trap

source

pub fn is<T: Error + 'static>(&self) -> bool

Returns true if the RuntimeError is the same as T
