Trait dyn_sized::DynSized

pub trait DynSized {
    type Meta: Copy;
    unsafe fn assemble(meta: Self::Meta, data: *const ()) -> *const Self;
    fn disassemble(ptr: *const Self) -> (Self::Meta, *const ());

    unsafe fn assemble_mut(meta: Self::Meta, data: *mut ()) -> *mut Self { ... }
    fn disassemble_mut(ptr: *mut Self) -> (Self::Meta, *mut ()) { ... }
    fn meta(&self) -> Self::Meta { ... }
    fn data(&self) -> *const () { ... }
    fn data_mut(&mut self) -> *mut () { ... }
}

A trait for dynamically sized types, similar in principle to the Sized trait. Allows conversion between fat and thin pointers.
