Struct PtyManager 

pub struct PtyManager { /* private fields */ }

Manages all active terminal sessions.

Stored by the frontend outside of its shared state to avoid reference cycles. Dropping PtyManager or calling PtyManager::shutdown closes all sessions gracefully.

Implementations

impl PtyManager

pub fn new() -> Self

Creates an empty manager with no raw-output tap (the TUI path).

pub fn with_raw_output(raw_output: Sender<(SessionId, Vec<u8>)>) -> Self

Creates an empty manager that also mirrors every session’s raw bytes into raw_output, keyed by SessionId (the GUI terminal tap). Sessions and the id space are identical to PtyManager::new; only the extra sink differs, so the TUI construction path is unaffected.

pub fn open( &mut self, host: &Host, cols: u16, rows: u16, tx: Sender<CoreEvent>, ) -> Result<SessionId>

Opens a new terminal tab for host and returns the assigned SessionId.

Returns immediately; the connection runs in a background task. Connection or auth errors surface later via CoreEvent::Error + PtyExited.

Errors

Currently infallible, but kept fallible so the caller’s error handling (and the public API) stays unchanged.

pub fn write(&mut self, id: SessionId, data: &[u8]) -> Result<()>

Sends raw bytes to the session identified by id. Unknown id is a no-op.

Errors

Infallible in practice; a dropped task is ignored like a closed session.

pub fn resize(&mut self, id: SessionId, cols: u16, rows: u16) -> Result<()>

Forwards a resize to the session identified by id. No-op if not found.

The vt100 parser is resized by the app layer; the task only relays window_change to the server.

Errors

Infallible; kept fallible to preserve the public signature.

pub fn close(&mut self, id: SessionId)

Closes and removes the session with the given id.

pub fn shutdown(self)

Gracefully shuts down all sessions.

pub fn parser_for(&self, id: SessionId) -> Option<Arc<Mutex<Parser>>>

Returns the parser Arc for the session with the given id, if any.

Trait Implementations

impl Default for PtyManager

fn default() -> Self

Returns the “default value” for a type.
