Struct Terminal 

pub struct Terminal {
    input_tx: Sender<Vec<u8>>,
    output_tx: Sender<Vec<u8>>,
    fd: Arc<AsyncFd<OwnedFd>>,
    child: Mutex<Option<Child>>,
    closed_rx: Receiver<bool>,
}

Async terminal backed by a real PTY.

Spawns two background tasks (read loop and write loop) that bridge the PTY fd with tokio channels. Sends SIGHUP to the child process on drop.

Fields

input_tx: Sender<Vec<u8>>

output_tx: Sender<Vec<u8>>

fd: Arc<AsyncFd<OwnedFd>>

child: Mutex<Option<Child>>

closed_rx: Receiver<bool>

Implementations

impl Terminal

pub fn spawn( shell: &str, pwd: Option<&Path>, ) -> Result<(Self, Receiver<Vec<u8>>)>

Spawn a shell process and return the terminal plus an initial output receiver.

If pwd is provided, the shell starts in that directory.

pub fn subscribe(&self) -> Receiver<Vec<u8>>

Subscribe to the terminal output broadcast channel.

pub fn closed(&self) -> Receiver<bool>

Returns a watch receiver that becomes true when the PTY read loop exits (shell died / PTY closed).

pub async fn write(&self, data: Vec<u8>) -> Result<(), String>

Queue bytes to be written to the PTY.

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

Set the PTY window size (rows x cols).

Trait Implementations

impl Drop for Terminal

fn drop(&mut self)

Executes the destructor for this type.
