Trait ToUSize

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

Trait defining instance method to_usize() : usize that provides a no-cost or low-cost conversion into usize.

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

Built-in Types

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

• usize;
• u8;
• u16 - if architecture is 16+ bits;
• u32 - if architecture is 32+ bits;
• u64 - if architecture is 64+ bits;
• u128 - if architecture is 128+ bits;
