Crate curfew 

curfew provides a deadline-aware fork-join abstraction for Rust.

The crate exposes two primary building blocks:

• DeadlineJoiner to manage groups of threads and collect only those completing before an absolute Instant deadline.
• join_with_deadline to attempt joining an individual JoinHandle before a deadline while still allowing late results to be recovered.
• Enable the tokio feature to unlock async counterparts (DeadlineJoinerAsync and join_with_deadline_async) with matching semantics.

All utilities operate entirely in safe Rust and gracefully skip work that runs past the deadline without attempting to cancel or terminate threads.
