Detailed Description

template<typename T>
struct Aleph::Aleph_Hash< T >

Primary hash functor used internally by dft_hash_fct / snd_hash_fct.

Resolution order (in priority):

1. ADL — calls aleph_hash_value(key) if found in T's namespace. This is the semantic path for user-defined types.
2. Byte — calls wyhash_hash for trivially-copyable, non-pointer T. This is the default path for scalars and POD structs.
3. Error — static_assert for any other T, with an actionable message.

Users may also fully specialize Aleph_Hash<MyType> as an alternative to ADL.

Template Parameters

T

Key type.
