Crate noxu_latch 

Internal component of the noxu database.

This crate is published only so the noxu umbrella crate can depend on it. Use noxu (noxu = "3") in applications; depend on this crate directly only if you are extending the engine internals. Its API may change without a major version bump.

Latching primitives for Noxu DB.

Latching primitives — exclusive and shared/exclusive latches used for B-tree node concurrency control.

Latches are expected to be held for short, defined periods of time. No deadlock detection is provided; it is the caller’s responsibility to sequence latch acquisition in an ordered fashion to avoid deadlocks.

Key properties:

• Uses noxu_sync for the underlying lock primitives
• Reentrancy prevention is enforced (panics on reentrant acquire)
• Thread ownership tracking is always available via noxu_sync

Structs

SharedLatchReadGuard

RAII guard for shared/read access. Releases when dropped.

SharedLatchWriteGuard

RAII guard for exclusive/write access. Releases when dropped.
