Crate hjkl_splash 

hjkl-splash — rendering-agnostic splash-screen animation.

Emits pure SplashCell items via an iterator; consumers (TUI/GUI) translate to their own rendering surface. The crate owns its time source — Splash::cells takes &self and reads the wall clock internally, so consumers cannot accidentally desynchronise the animation by skipping a per-iteration advance() call (the v0.1 footgun).

Modules

presets

Built-in presets for the hjkl-splash animation.

start_screen

High-level StartScreen wrapper for consumers that want a ready-to-use splash animation wired to app palette colours.

Structs

Layout

Bounding box of the art block within the terminal/canvas.

Rgb

24-bit RGB colour value.

Splash

The animation state machine.

SplashCell

A single cell to be painted this tick.

Enums

CellKind

Describes what role a cell plays in the current animation frame.

Constants

DEFAULT_PERIOD

Default tick period — ~8 Hz (120 ms). Matches the canonical hjkl feel (in v0.1 and earlier, manual advance() was driven by a 120 ms poll timeout in the consumer’s event loop, so this preserves that cadence by default). Consumers wanting smoother motion can opt in via Splash::with_period.

DEFAULT_TRAIL_LEN

Default trail length.

Functions

default_trail_color

Default ramp for trail age → Rgb.
