TerminalGuard

mermaid_cli::app::terminal

Struct TerminalGuard 

Source 
pub struct TerminalGuard { /* private fields */ }
Expand description

Owned terminal that restores the shell on drop.

Construct once at the top of app::run; keep it alive for the duration of the main loop; let it drop. Do not construct twice (the second enable_raw_mode() is idempotent but the second EnterAlternateScreen stacks).

Implementations§

Source§

impl TerminalGuard

Source

pub fn setup() -> Result<Self>

Take over the terminal: raw mode, alternate screen, mouse, bracketed paste, focus events.

§Errors

Enabling raw mode, entering the alternate screen and enabling the input modes, and building the backing Terminal. A failure after raw mode is on restores the terminal before returning, so an Err never leaves the shell in raw mode. A terminal without the kitty keyboard protocol is not an error — that probe degrades to the legacy encoding.

Source

pub fn inner_mut(&mut self) -> &mut Terminal<CrosstermBackend<Stdout>>

Mutable access for the render pass.

Source

pub fn restore_now(&mut self)

Restore terminal state now. Idempotent so normal exit, signal exit, and Drop can all share the same call site safely.
