Required Methods§

fn new_uninit_() -> Box<MaybeUninit<T>>
where T: Sized,

Box::new_uninit

See https://github.com/rust-lang/rust/issues/63291

fn new_zeroed_() -> Box<MaybeUninit<T>>
where T: Sized,

Box::new_zeroed

See https://github.com/rust-lang/rust/issues/63291

unsafe fn assume_init_(this: Box<MaybeUninit<T>>) -> Box<T>
where T: Sized,

Box::assume_init

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.
