Module file_lock 

Facade: bounded advisory file locks live in the lean-ctx-fs crate.

Structs

Turn

One thread’s turn at a lock path within this process; the next waiter in line gets it when this drops.

Functions

acquire_exclusive_timeout

Takes an exclusive advisory lock, giving up after timeout rather than waiting for as long as the other holder cares to keep it.

is_contended

take_turn

Wait for this thread’s turn at path among the threads of this process. None once timeout passed without any turn being handed over.
