Struct UnixMasterPty 

pub struct UnixMasterPty { /* private fields */ }

Represents the master end of a pty. The file descriptor will be closed when the Pty is dropped.

Trait Implementations

impl MasterPty for UnixMasterPty

fn resize(&self, size: PtySize) -> Result<(), Error>

Inform the kernel and thus the child process that the window resized. It will update the winsize information maintained by the kernel, and generate a signal for the child to notice and update its state.

fn get_size(&self) -> Result<PtySize, Error>

Retrieves the size of the pty as known by the kernel

fn try_clone_reader(&self) -> Result<Box<dyn Read + Send>, Error>

Obtain a readable handle; output from the slave(s) is readable via this stream.

fn take_writer(&self) -> Result<Box<dyn Write + Send>, Error>

Obtain a writable handle; writing to it will send data to the slave end. Dropping the writer will send EOF to the slave end. It is invalid to take the writer more than once.

fn as_raw_fd(&self) -> Option<RawFd>

If get_termios() and process_group_leader() are both implemented and return Some, then as_raw_fd() should return the same underlying fd associated with the stream. This is to enable applications that “know things” to query similar information for themselves.

fn tty_name(&self) -> Option<PathBuf>

fn process_group_leader(&self) -> Option<pid_t>

If applicable to the type of the tty, return the local process id of the process group or session leader

fn get_termios(&self) -> Option<Termios>

If applicable to the type of the tty, return the termios associated with the stream
