[−][src]Struct wasmer_engine::RuntimeError
A struct representing an aborted instruction execution, with a message indicating the cause.
Implementations
impl RuntimeError
[src]
pub fn new<I: Into<String>>(message: I) -> Self
[src]
Creates a new generic RuntimeError
with the given message
.
Example
let trap = wasmer_engine::RuntimeError::new("unexpected error"); assert_eq!("unexpected error", trap.message());
pub fn from_trap(trap: Trap) -> Self
[src]
Create a new RuntimeError from a Trap.
pub fn raise(error: Box<dyn Error + Send + Sync>) -> !
[src]
Raises a custom user Error
pub fn message(&self) -> String
[src]
Returns a reference the message
stored in Trap
.
pub fn trace(&self) -> &[FrameInfo]
[src]
Returns a list of function frames in WebAssembly code that led to this trap happening.
pub fn downcast<T: Error + 'static>(self) -> Result<T, Self>
[src]
Attempts to downcast the RuntimeError
to a concrete type.
pub fn is<T: Error + 'static>(&self) -> bool
[src]
Returns true if the RuntimeError
is the same as T
