Detailed Description

Semantic placeholder for mutex_like types.

A zero-cost, fully concept-compatible dummy mutex. All locking functions are implemented as no-ops, and all try_* operations always return true.

This type serves as a semantic stand-in for real synchronization primitives in contexts where locking is structurally required but semantically unnecessary — for example, when thread safety is guaranteed by design or when the data is confined to a single thread.

Concept compatibility:

It is analogous in spirit to std::nullptr_t: the type exists for semantic consistency, but creating distinct instances is meaningless. Use the provided global constant jh::typed::null_mutex instead.

See also: jh::typed::null_mutex; jh::concepts::mutex_like; jh::sync::const_lock
