Trait FromVal

pub trait FromVal: Sized {
    // Required methods
    fn from_val(v: &Val) -> Self;
    fn take_ownership(v: Handle) -> Self;
    fn as_handle(&self) -> Handle;
}

Required Methods

fn from_val(v: &Val) -> Self

Creates a Val object from another

fn take_ownership(v: Handle) -> Self

Takes the ownership of a handle

fn as_handle(&self) -> Handle

Returns the raw js handle

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
