Struct PhantomDrop

pub(crate) struct PhantomDrop<T>(PhantomData<T>);

Expand description

A cute utility type that works just like PhantomData, but also implements Drop. This forces any lifetimes that are associated with the type to be used until the Drop impl is ran. This prevents lifetimes from being shortened.
