Struct mm0_util::SliceUninit [−][src]
pub struct SliceUninit<T>(_);
A way to initialize a Box<[T]> by first constructing the array (giving the length),
initializing the elements in some order, and then using the unsafe function
assume_init to assert that every element of the array has been initialized and
transmute the SliceUninit<T> into a Box<[T]>.
Implementations
impl<T> SliceUninit<T>[src]
#[must_use]pub fn new(size: usize) -> Self[src]
#[must_use]
pub fn new(size: usize) -> SelfCreate a new uninitialized slice of length size.
pub fn set(&mut self, i: usize, val: T)[src]
Assign the value val to location i of the slice. Warning: this does not
call the destructor for T on the previous value, so this should be used only
once per location unless T has no Drop impl.
#[must_use]pub unsafe fn assume_init(self) -> Box<[T]>[src]
#[must_use]
pub unsafe fn assume_init(self) -> Box<[T]>Finalizes the construction, returning an initialized Box<[T]>.
Safety
This causes undefined behavior if the content is not fully initialized.
