Struct LiveConfig 

pub struct LiveConfig {
    pub rows: usize,
    pub cols: usize,
    pub scrollback: usize,
}

How the live console lays out and truncates tiles.

The console does not auto-detect the terminal width or react to resizes: cols is a fixed tile width the caller supplies once. Passing a value that does not match the real terminal only over- or under-truncates the tiles; it never corrupts output, since every tile line is clamped to cols.

Fields

rows: usize

Maximum content rows a region tile may occupy — the height of its virtual terminal and the cap a tile grows to. A tile does not reserve this height: it starts at just its header and grows with its content up to this many rows (see LiveConsole::feed), so a silent or short-lived region stays small instead of padding out a tall empty block.

cols: usize

Terminal columns: the tile width. A child’s output is applied to a grid sized to the visible content area (this width minus the content indent), so a real width must be passed (unlike the old truncation width, 0 is not “disable”).

scrollback: usize

How many rows that scroll off a tile are retained per region for a failure replay. The live tile stays a bounded peek; on failure this many of the most-recent scrolled-off rows (plus the final on-screen rows) are flushed to scrollback as the failure block. 0 retains nothing, so a failure replays only the rows still on screen.

Implementations

impl LiveConfig

pub fn content_cols(&self) -> usize

The inner virtual-terminal grid width: the tile width minus the content indent rendered under each region header.

A child whose output is fed to the tile must be told its terminal is this wide (not the full tile width), so its own line wrapping matches the grid. Otherwise a full-width in-place progress redraw wraps at the grid edge, scrolls the short grid, and churns the retained failure tail with stale half-frames on every tick — which then surface in the bounded replay when a region fails.
