Crate katui_rt 

The katui runtime: the one impure layer. It owns the controlling terminal, the raw-mode lifecycle, the frame clock, the event pump and the interactive loop. Everything pure lives in the crates below.

Modules

app

The interactive event loop: redraws when something changed and sleeps otherwise, on the alternate screen with the mouse enabled.

clock

The frame clock: fixed-frame deadlines, where a frame that misses its slot restarts the schedule so a stall never ends in a burst.

events

The event pump: terminal input on its own thread and messages from the application’s own threads, merged into one queue.

headless

A headless driver: runs an App with no terminal, so a test can type bytes, deliver messages, resize the screen and read back every frame’s bytes.

info

The capability card katui-info prints: one line per fact, the graphics backend first, chosen through the same selection every other consumer uses.

media

Raw video from a child process: a decoder writes RGBA frames to its standard output, a reader thread queues them, and the stream hands out the newest frame its clock has reached.

pacing

Output pacing: writes frames in step with what the terminal has actually consumed, so nothing queues up behind a slow terminal.

pane

Where our multiplexer pane stands. A multiplexer drops graphics from panes that are unfocused or out of view, so an application pauses there and sends everything again when the pane comes back.

session

The alternate-screen session guard: enter on construction, leave on drop, including unwinds. A session owns its writer; drawing through katui happens beside it, on the same stdout.

tty

The controlling-terminal transport: the probe’s read and write side, in raw mode for the exchange and restored after it.

Enums

RtError

Failures of the terminal lifecycle: the crate’s one error enum.
