Struct Throw

pub struct Throw(/* private fields */);

A unit type indicating that the JavaScript thread is throwing an exception.

Throw deliberately does not implement std::error::Error. It’s not recommended to chain JavaScript exceptions with other kinds of Rust errors, since throwing means that the JavaScript thread is unavailable until the exception is handled.

Implementations

impl Throw

pub unsafe fn new() -> Self

Creates a Throw struct representing a JavaScript exception state.

Safety

Throw should only be constructed when the JavaScript VM is in a throwing state. I.e., when Status::PendingException is returned.
