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

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

Implementations§

Creates a new generic RuntimeError with the given message.

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

Create a new RuntimeError from a Trap.

Creates a custom user Error.

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

Returns a reference the message stored in Trap.

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

Attempts to downcast the RuntimeError to a concrete type.

Returns trap code, if it’s a Trap

Returns true if the RuntimeError is the same as T
