Struct Tui 

pub struct Tui { /* private fields */ }

Ported from TUI. Go’s program/ready/done fields (the Bubble Tea program handle and its lifecycle channels) become, respectively: a channel Sender<TuiEvent> the running event loop listens on (tx), and two AtomicBools (ready/done) standing in for Go’s closed-channel-as-signal idiom. filter is unchanged from the pre-existing port.

Implementations

impl Tui

pub fn new() -> Self

Ported from NewTUI.

pub fn start(&self, out: Box<dyn Write + Send>) -> Result<(), TuiError>

Ported from TUI.Start. Takes &self rather than Go’s method receiver’s implicit &mut: Tui is shared via Arc<Tui> (see Context), so quit/println must be callable from other threads while this runs its event loop, exactly the situation Go’s version handles with its own program/ready/done fields – interior mutability (the Mutex/AtomicBool fields above) plays the same role here.

Sets up a ratatui terminal with a one-line inline viewport (Viewport::Inline(1)), matching Go’s tea.Println pattern: log lines print permanently above the viewport via Terminal::insert_before, and the viewport itself always shows the current filter status line. Blocks until a quit is requested (either Ctrl-C typed into the terminal or Tui::quit called from elsewhere), matching Go’s program.Run() blocking semantics.

pub fn quit(&self)

Ported from TUI.Quit. Go’s waitReady blocks the caller up to 5 seconds waiting for start to have run at least once before quitting; this port instead checks the ready flag immediately and no-ops if start hasn’t set it yet (or has already cleared it on exit), which preserves the safety guarantee (“calling quit before/after start never panics or blocks”) without actually blocking a test for 5 wall-clock seconds.

pub fn println(&self, line: &str)

Ported from TUI.Println. Writes directly to the stored output if the TUI has already stopped (mirrors Go’s done channel check); otherwise forwards the colorized line into the running event loop’s channel. No-ops if start was never called, mirroring Go’s ready select-default-return.

pub fn filter(&self) -> String

Ported from TUI.Filter.

pub fn matches(&self, line: &str) -> bool

Ported from TUI.Matches.

pub fn new_writer(self: &Arc<Self>) -> TuiWriter

Ported from NewWriter/tuiWriter. Returns a Write implementation that forwards each line written to it (minus a single trailing newline, matching Go’s strings.TrimSuffix) to Tui::println.
