#[repr(transparent)]
pub struct Opaque<T>(_);

Expand description

Stores an opaque value.

This is meant to be used with FFI objects that are never interpreted by Rust code.

Implementations

source

impl<T> Opaque<T>

source

pub const fn new(value: T) -> Self

Creates a new opaque value.

source

pub const fn uninit() -> Self

Creates an uninitialised value.

source

pub fn get(&self) -> *mut T

Returns a raw pointer to the opaque data.
