Trait PtyMaster 

pub trait PtyMaster: Send + 'static {
    // Required methods
    fn try_clone_reader(&mut self) -> Result<Box<dyn Read + Send>>;
    fn take_writer(&mut self) -> Result<Box<dyn Write + Send>>;
    fn resize(&self, size: PtySize) -> Result<()>;
    fn get_size(&self) -> Result<PtySize>;
    fn process_group_leader(&self) -> Option<i32>;
}

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

Required Methods

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

Clone a reader for PTY output.

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

Take the writer used to send input to the PTY.

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

Resize the PTY to the requested dimensions.

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

Return the current PTY dimensions. On Windows the value is the last size passed to resize (or the initial openpty size); ConPTY exposes no live query API. Restored in 4.0.1 for downstream parity with portable-pty’s MasterPty::get_size.

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

On Unix returns the foreground process group leader of the PTY (used by tools like tcsetpgrp checks). Always returns None on Windows where the concept doesn’t exist.

Dyn Compatibility

This trait is dyn compatible.

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