Trait MaybeIndexUnchecked 

pub trait MaybeIndexUnchecked<T> {
    // Required methods
    fn at(&self, id: usize) -> &T;
    fn at_mut(&mut self, id: usize) -> &mut T;
    fn read(&self, id: usize) -> T;
    fn write(&mut self, id: usize, data: T);
}

Indexing trait that optionally removes bounds checks on GPU targets.

When the unsafe_remove_boundchecks feature is enabled, methods use unchecked indexing for performance on SPIR-V and CUDA targets. Otherwise, standard bounds-checked indexing is used.

Required Methods

fn at(&self, id: usize) -> &T

Returns a reference to the element at id.

fn at_mut(&mut self, id: usize) -> &mut T

Returns a mutable reference to the element at id.

fn read(&self, id: usize) -> T

Copies and returns the element at id.

fn write(&mut self, id: usize, data: T)

Writes data to the element at id.

Dyn Compatibility

This trait is dyn compatible.

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