Trait KnownSize 

pub trait KnownSize {
    // Required method
    fn size(p: *const Self) -> usize;
}

Trait to represent compile-time known size information.

This is a generalization of size_of that works for dynamically sized types.

Required Methods

fn size(p: *const Self) -> usize

Get the size of an object of this type in bytes, with the metadata of the given pointer.

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