Trait AsUSize 

pub trait AsUSize {
    // Required method
    fn as_usize(&self) -> usize;
}

Trait defining instance method as_usize() : usize that provides a cost-free conversion into usize.

It is expected that the implementing type “is-a” usize in a direct manner as well as in a logical manner.

Built-in Types

If the feature "implement-AsUSize-for-built_ins" is defined (as it is by "default"), then this is also implemented for the following type(s):

• usize;

Required Methods

fn as_usize(&self) -> usize

Dyn Compatibility

This trait is dyn compatible.

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