This release deprecates TypeCmp::with_any and TypeNe::with_any due to an unsoundness bug.

Changelog

1.9.0

Deprecated {TypeCmp, TypeNe}::with_any due to unsoundness: both constructors rely on TypeId::of::<L>() != TypeId::of::<R>() implying L != R, which is not true in the general case.

Deprecated {TypeCmp, TypeNe}::with_any due to unsoundness: both constructors rely on TypeId::of::<L>() != TypeId::of::<R>() implying L != R, which is not true in the general case.

This release includes many new features, with these as the main ones:

• injective type-level functions
• TypeCmp enum for representing "TypeEq or TypeNe"
• Parity of TypeEq APIs in TypeNe
• more generic free function equivalents of TypeCmp/TypeEq/TypeNe methods in methods module
