Module loader 

Loading indicators for splash and loading screens.

Pure functions operating on raw RGB565 byte buffers. All take explicit screen dimensions so they are reusable by any crate without global state.

• paint_loading_bar - horizontal progress bar at the bottom of the screen

There used to be a rotating-arc spinner here. It was removed: a rotating arc drives every pixel in its ring from black to white and back, continuously, for as long as loading takes. Non-monotone and unbounded is the worst case this panel can be given, and no amount of tuning the rate fixed it. The splash now reveals its wordmark one piece at a time instead, so each pixel changes state exactly once (see rendering::splash in the app crate).

A progress bar only ever fills in one direction, so it stays valid.

Structs

Rect

A screen rectangle (x, y, width, height) in pixels, for partial-refresh bounding regions.

Functions

box_downscale

Area-average downscale of an RGB888 buffer.

loading_bar_rect

Bounding rectangle of the loading bar for partial-refresh updates, with a small margin so the refresh band covers the full bar including anti-aliasing edges.

paint_loading_bar

Draw a horizontal progress bar at the bottom of the screen.
