Trait Length 

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

Values that have a length (see Len and NonEmpty).

The length of strings is the number of characters, of collections the number of items.

Required Methods

fn length(&self) -> usize

Returns the length.

Dyn Compatibility

This trait is dyn compatible.

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