//! [`TerminalSessions`] — the active-terminal registry (application service).
|
|
//!
|
|
//! Maps a [`SessionId`] to the live [`PtyHandle`] and the [`TerminalSession`]
|
|
//! snapshot. Thread-safe (behind a [`Mutex`]); a single instance is shared
|
|
//! (as `Arc`) by all terminal use cases via the composition root. See the module
|
|
//! docs in `terminal/mod.rs` for the rationale of keeping this in the
|
|
//! application layer rather than the domain or the adapter.
