Module core_extensions::phantom_variances

Contains many type aliases for PhantomData with different lifetime variances.

These aliases can be constructed in these ways:

• PhantomData

• Variance::<T>::default()

• value.ty_() constructs VariantPhantom

• value.ty_d() constructs VariantDropPhantom

• value.ty_inv() constructs InvariantPhantom

• value. ty_inv_ref() constructs InvariantRefPhantom

Phantom type lifetime variance type variance

VariantDropPhantom - variant (with drop check) VariantPhantom - variant InvariantRefPhantom invariant - InvariantPhantom - invariant

Type Definitions

InvariantPhantom	Type alias for an invariant PhantomData.
InvariantRefPhantom	Type alias for an PhantomData with an invariant lifetime.
VariantDropPhantom	Type alias for a variant PhantomData with drop check.
VariantPhantom	Type alias for a variant PhantomData withhout drop-check.
