// file: src/event/one_shot.rs
//! One-shot channel implementation using flume::bounded(1).
//!
//! Follows the same pattern as `unbound.rs` for consistency.
//! Senders and receivers are consumed on use, as is typical for one-shot channels.
//!
//! Example wraping the Tex
//! ```rust
//! #[derive(Clone, From, Deref)]
//! pub struct RunDoneTx(OneShotTx<RunResponse>);
//! ```
