Generic wrapper around a view.

Default implementation forwards all calls to the child view. Overrides some methods as desired.

You can use the wrap_impl! macro to define with_view and with_view_mut for you.

Associated Types

Type that this view wraps.

Required Methods

Runs a function on the inner view, returning the result.

Returns None if the inner view is unavailable. This should only happen with some views if they are already borrowed by another call.
