Function uninit_buf

pub fn uninit_buf<T, const N: usize>() -> [MaybeUninit<T>; N]

Create an array of unintialized memory

This function is just a safe wrapper around MaybeUninit::uninit().assume_init(), which is safe when used to create a [MaybeUninit<T>; N], since this type explicitly requires no initialization

let mut buffer = uninit_buf::<i32, 1000>();

for elem in &mut buffer {
  elem.write(123);
}

let result = unsafe { mark_initialized(buffer) };
assert_eq!(result, [123; 1000])

This is similar to the nightly-only core::mem::MaybeUninit::uninit_array
