Struct RawModeGuard 

pub struct RawModeGuard { /* private fields */ }

RAII guard that saves the original termios and restores it on drop.

This is the foundation for panic-safe terminal cleanup: even if the application panics, the Drop impl runs (unless panic = "abort") and the terminal returns to its original state.

The guard opens /dev/tty to get an owned fd that is valid for the lifetime of the guard, avoiding unsafe BorrowedFd construction.

Implementations

impl RawModeGuard

pub fn enter() -> Result<Self>

Enter raw mode on the controlling terminal, returning a guard that restores the original termios on drop.

pub fn enter_on(tty: File) -> Result<Self>

Enter raw mode on a specific terminal file (e.g., a PTY slave for testing).
