Trait HasLength 

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

Represents types that have length defined for their values.

Required Methods

fn length(&self) -> usize

Returns the value length.

Dyn Compatibility

This trait is dyn compatible.

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