Crate typeless

unsafe API for type erasure on the stack

Storing any value x of type T in TypeErased completely destroys all type data associated with it.

Restrictions

While this erases all type data, leaving only the pure bytes, the compiler still requires 2 things:

• Size: The size of a TypeErased is not based on the data it contains, but rather a const generic parameter C, effectively a “maximum size” on the types it can contain.

• Alignment: Until there is a way to define alignment by a const parameter, the alignment of TypeErased is 8 bytes, so anything with an alignment of 8 or less can be contained

Access

Since there is no type data anymore, any access to the inner data is unsafe (except getting the bytes directly)

TypeErased is not Send nor Sync since it can’t be known if that’s safe
