Trait ExactSize 

pub trait ExactSize {
    // Required method
    fn exact_size(&self) -> Size;
}

A type with a known size in bits and refs.

Required Methods

fn exact_size(&self) -> Size

Exact size of the value when it is stored in a slice.

Dyn Compatibility

This trait is dyn compatible.

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