Struct wasmer::RuntimeError
source · [−]pub struct RuntimeError { /* private fields */ }
Expand description
A struct representing an aborted instruction execution, with a message indicating the cause.
Implementations
sourceimpl RuntimeError
impl RuntimeError
sourcepub fn new<I>(message: I) -> RuntimeError where
I: Into<String>,
pub fn new<I>(message: I) -> RuntimeError where
I: Into<String>,
Creates a new generic RuntimeError
with the given message
.
Example
let trap = wasmer_engine::RuntimeError::new("unexpected error");
assert_eq!("unexpected error", trap.message());
sourcepub fn from_trap(trap: Trap) -> RuntimeError
pub fn from_trap(trap: Trap) -> RuntimeError
Create a new RuntimeError from a Trap.
sourcepub fn raise(error: Box<dyn Error + Sync + Send + 'static, Global>) -> !
👎 Deprecated since 2.1.1: return a Result from host functions instead
pub fn raise(error: Box<dyn Error + Sync + Send + 'static, Global>) -> !
return a Result from host functions instead
Raises a custom user Error
sourcepub fn user(
error: Box<dyn Error + Sync + Send + 'static, Global>
) -> RuntimeError
pub fn user(
error: Box<dyn Error + Sync + Send + 'static, Global>
) -> RuntimeError
Creates a custom user Error.
This error object can be passed through Wasm frames and later retrieved
using the downcast
method.
sourcepub fn trace(&self) -> &[FrameInfo]
pub fn trace(&self) -> &[FrameInfo]
Returns a list of function frames in WebAssembly code that led to this trap happening.
sourcepub fn downcast<T>(self) -> Result<T, RuntimeError> where
T: 'static + Error,
pub fn downcast<T>(self) -> Result<T, RuntimeError> where
T: 'static + Error,
Attempts to downcast the RuntimeError
to a concrete type.
