Trait Handle 

pub trait Handle: Sized {
    const TYPE: ObjectType;

    // Required methods
    fn as_raw(self) -> u64;
    fn from_raw(_: u64) -> Self;

    // Provided method
    fn is_null(self) -> bool { ... }
}

Required Associated Constants

const TYPE: ObjectType

Required Methods

fn as_raw(self) -> u64

fn from_raw(_: u64) -> Self

Provided Methods

fn is_null(self) -> bool

Returns whether the handle is a NULL value.

Example

let instance = Instance::null();
assert!(instance.is_null());

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety".
