Struct TerminalManager 

pub struct TerminalManager { /* private fields */ }

Manages the terminal lifecycle: raw mode, alternate screen, and rendering.

Guarantees terminal state restoration on drop (normal exit, error, or panic). The panic hook installed via install_panic_hook provides an additional safety net for restoration before the panic message is printed.

Implementations

impl TerminalManager

pub fn new() -> Result<Self>

Initialize terminal: enable raw mode, switch to alternate screen, hide cursor.

This must be called before any rendering. The terminal is restored automatically when the TerminalManager is dropped.

pub fn restore(&mut self) -> Result<()>

Restore the terminal to its original state: disable raw mode, leave alternate screen, show cursor.

pub fn draw<F>(&mut self, f: F) -> Result<()>

where F: FnOnce(&mut Frame<'_>),

Draw a single frame. On terminal resize, ratatui automatically picks up the new dimensions from the backend, so calling draw after a resize event produces a correctly laid-out frame.

pub fn size(&self) -> Result<Rect>

Return the current terminal size as a Rect.

Trait Implementations

impl Drop for TerminalManager

fn drop(&mut self)

Executes the destructor for this type.

fn pin_drop(self: Pin<&mut Self>)

🔬This is a nightly-only experimental API. (pin_ergonomics)

Execute the destructor for this type, but different to Drop::drop, it requires self to be pinned.
