Trait IndexUnchecked 

pub trait IndexUnchecked<T> {
    // Required methods
    unsafe fn index_unchecked(&self, index: usize) -> &T;
    unsafe fn index_unchecked_mut(&mut self, index: usize) -> &mut T;
}

Index into an array without bounds checking.

The main purpose of this trait is to work around the fact that the regular get_unchecked* methods do not work in in SPIR-V.

Required Methods

unsafe fn index_unchecked(&self, index: usize) -> &T

Returns a reference to the element at index. The equivalent of get_unchecked.

Safety

Behavior is undefined if the index value is greater than or equal to the length of the array.

unsafe fn index_unchecked_mut(&mut self, index: usize) -> &mut T

Returns a mutable reference to the element at index. The equivalent of get_unchecked_mut.

Safety

Behavior is undefined if the index value is greater than or equal to the length of the array.

Dyn Compatibility

This trait is dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety".
