Struct TerminalGrid 

pub struct TerminalGrid { /* private fields */ }

A terminal grid fed incrementally with raw PTY bytes. The daemon (Wave 3) owns one per PTY-managed agent and feeds it from the PTY drainer’s ring; a ReadinessDetector inspects its snapshot to decide whether the CLI is ready.

Implementations

impl TerminalGrid

pub fn new(rows: u16, cols: u16) -> Self

Construct a grid of the given size. Zero dimensions are clamped to 1 so the parser never panics on a degenerate winsize.

pub fn with_default_size() -> Self

Construct a grid at the 24x80 default size.

pub fn feed(&mut self, bytes: &[u8])

Feed raw PTY output. Safe to call with partial escape sequences split across reads; the underlying vte parser buffers incomplete sequences between advance calls.

pub fn resize(&mut self, rows: u16, cols: u16)

Resize the grid, mirroring a PTY winsize change. Dimensions are clamped to 1.

pub fn snapshot(&self) -> OwnedScreen

Snapshot the current screen into an owned holder a ScreenView can borrow from. visible_text is plain text (no formatting): one line per grid row with trailing blank cells trimmed, exactly what a human would see and what the readiness detectors substring-match against. Cursor is 0-indexed (row, col) (preserved from the prior vt100 contract).
