Trait Projection 

pub trait Projection {
    type Source: ?Sized;
    type Target: ?Sized;

    // Required methods
    fn offset(&self, meta: <Self::Source as Pointee>::Metadata) -> usize;
    fn project_metadata(
        &self,
        meta: <Self::Source as Pointee>::Metadata,
    ) -> <Self::Target as Pointee>::Metadata;
}

Required Associated Types

type Source: ?Sized

type Target: ?Sized

Required Methods

fn offset(&self, meta: <Self::Source as Pointee>::Metadata) -> usize

fn project_metadata( &self, meta: <Self::Source as Pointee>::Metadata, ) -> <Self::Target as Pointee>::Metadata

Dyn Compatibility

This trait is dyn compatible.

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