Trait possibly_uninit::BorrowUninit[−][src]

pub unsafe trait BorrowUninit<Borrowed> {
    fn borrow_uninit(&self) -> &MaybeUninit<Borrowed>;

    unsafe fn assume_init_ref(&self) -> &Borrowed { ... }
}

Trait allowing borrowing of MaybeUninit<T> values.

It’s analogous to core::borrow::Borrow, expect it works with MaybeUninit values.

Required methods

fn borrow_uninit(&self) -> &MaybeUninit<Borrowed>[src]

Borrows maybe uninitialized value.

This method is only useful for implementing assume_init_ref.

Provided methods

unsafe fn assume_init_ref(&self) -> &Borrowed[src]

Converts the reference assuming it’s initialized.

Safety

Calling this method on uninitialized value is undefined behavior.
