Add rough `destruct_into_heads` function #105

Draft

erikjohnston wants to merge 1 commit into someguynamedjosh:main from erikjohnston:erikj/destruct_into_heads

erikjohnston commented Dec 8, 2023

A rough implementation of #104.

Adds:

a new struct OwnedTailFields which is a struct that contains all tail fields.
a new method fn destruct_into_heads<R>(self, user: impl for<'this> FnOnce(OwnedTailFields<'this>) -> R) -> (R, Heads).

This allows calling functions on borrowed fields that take self. See the example for... an example.
