Struct rustc_data_structures::tagged_ptr::copy::CopyTaggedPtr[−][src]

pub struct CopyTaggedPtr<P, T, const COMPARE_PACKED: bool> where
    P: Pointer,
    T: Tag,  {
    packed: NonZeroUsize,
    data: PhantomData<(P, T)>,
}

A Copy TaggedPtr.

You should use this instead of the TaggedPtr type in all cases where P: Copy.

If COMPARE_PACKED is true, then the pointers will be compared and hashed without unpacking. Otherwise we don’t implement PartialEq/Eq/Hash; if you want that, wrap the TaggedPtr.
