pub struct PtyManager { /* private fields */ }

Implementations

impl PtyManager

pub fn new() -> Self

pub fn with_signal_handler(on_signal: SignalHandler) -> Self

pub fn create_pty(&self) -> PtyPair

pub fn create_pty_fds( &self, fd_table: &mut ProcessFdTable, ) -> FdResult<(u32, u32, String)>

pub fn poll( &self, description_id: u64, requested: PollEvents, ) -> PtyResult<PollEvents>

pub fn write( &self, description_id: u64, data: impl AsRef<[u8]>, ) -> PtyResult<usize>

pub fn read( &self, description_id: u64, length: usize, ) -> PtyResult<Option<Vec<u8>>>

pub fn read_with_timeout( &self, description_id: u64, length: usize, timeout: Option<Duration>, ) -> PtyResult<Option<Vec<u8>>>

pub fn close(&self, description_id: u64)

pub fn is_pty(&self, description_id: u64) -> bool

pub fn is_slave(&self, description_id: u64) -> bool

pub fn set_discipline( &self, description_id: u64, config: LineDisciplineConfig, ) -> PtyResult<()>

pub fn set_raw_mode( &self, description_id: u64, lease_owner_pid: Option<u32>, enabled: bool, ) -> PtyResult<Option<u64>>

Apply or release raw mode for a process. A foreground owner receives a generation-scoped lease so teardown can recover the exact attributes it inherited without letting an unrelated child restore a stale snapshot.

lease_owner_pid = None applies the requested mode but deliberately does not register teardown recovery (used for a background process).

pub fn release_raw_mode( &self, description_id: u64, owner_pid: u32, generation: u64, ) -> PtyResult<bool>

Release a particular foreground raw-mode lease during process cleanup. Returns whether the lease still existed. A stale/non-top release never changes live terminal attributes; its restore point is transferred to the next owner so out-of-order child exits still unwind correctly.

pub fn get_termios(&self, description_id: u64) -> PtyResult<Termios>

pub fn set_termios( &self, description_id: u64, termios: PartialTermios, ) -> PtyResult<()>

pub fn set_foreground_pgid( &self, description_id: u64, pgid: u32, ) -> PtyResult<()>

pub fn get_foreground_pgid(&self, description_id: u64) -> PtyResult<u32>

pub fn window_size(&self, description_id: u64) -> PtyResult<PtyWindowSize>

pub fn resize( &self, description_id: u64, cols: u16, rows: u16, ) -> PtyResult<Option<u32>>

pub fn pty_count(&self) -> usize

pub fn buffered_input_bytes(&self) -> usize

pub fn buffered_output_bytes(&self) -> usize

pub fn pending_read_waiter_count(&self) -> usize

pub fn queued_read_waiter_count(&self) -> usize

pub fn path_for(&self, description_id: u64) -> Option<String>
