Trait PtyMaster

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

Platform-neutral handle for the master side of a pseudo-terminal.

Required Methods

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

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

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

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

Provided Methods

fn process_group_leader(&self) -> Option<i32>

👎Deprecated:

use facade PTY control operations; removal planned for 5.0

Legacy Unix process-group accessor retained for source compatibility.

Platform mechanics do not consume this value; use facade operations for control. This method will be removed in the next major release.

fn as_raw_fd(&self) -> Option<i32>

👎Deprecated:

use facade PTY operations; removal planned for 5.0

Legacy Unix descriptor accessor retained for source compatibility.

The primitive representation avoids a host-native type in the neutral signature, and shared callers must not use it for platform mechanics.

fn interrupt_target(&self) -> Result<PtyInterruptTarget, Error>

Prepare an owned interrupt operation using the selected host’s PTY mechanics.

fn kill_process_group(&self) -> Result<(), Error>

Kill the selected host’s PTY process group, when one exists.

fn preferred_pid(&self, child: &(dyn PtyChild + 'static)) -> Option<u32>

Select the externally meaningful PID for this PTY.

Dyn Compatibility

This trait is dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety".
