stackpin

This crate exposes a StackPinned type that allows to represent !Unpin data that should be pinned to the stack at the point of declaration.

To do so, this crate provides a FromUnpinned trait and a stack_let! macro that enable safe construction of Pin<StackPinned> objects (aliased to PinStack for short).

Getting instances pinned at the point of declaration is as easy as:

stack_let!(unmovable = Unmovable::new_unpinned("Intel the Beagle")); // this creates the unmovable instance on the stack and binds `unmovable` with a `PinStack<Unmovable>`

For Unmovable a struct implementing the FromUnpinned<String> trait.

See the crate documentation for details, or look directly at the examples.
