Trait WriteThroughCursor
pub trait WriteThroughCursor: SizedTrait used to allow indirect implementation of Write for Cursor<Self>.
Since Cursor is not a foundational type, it is not possible to implement
Write for Cursor<T> if Write is defined in libcore and T is in a
downstream crate (e.g., liballoc or libstd).
Methods are identical in purpose and meaning to their Write namesakes.
