Crate onedrop_gui 

OneDrop GUI - Graphical user interface for MilkDrop visualizations

Modules

keymap 🔒

Keyboard → action mapping for the OneDrop GUI.

options_ui 🔒

egui-based Options overlay rendered on top of the MilkDrop visuals.

settings 🔒

Persistent user settings for the OneDrop GUI.

Structs

App 🔒

Args 🔒

Command-line arguments for onedrop-gui.

Blit 🔒

Fullscreen-triangle blit that samples the engine’s final display texture and writes to the swapchain. Sampling (rather than copy_texture_to_texture) sidesteps two failure modes: it doesn’t need COPY_DST on the swapchain (not guaranteed on all platforms), and sRGB conversion happens automatically when source and destination formats disagree.

Functions

apply_options_actions 🔒

Apply one frame’s worth of Options-panel changes to the live engine. Each field of OptionsActions is Some only when the user just moved that widget, so the function is a series of cheap no-ops on quiet frames.

beat_mode_from_name 🔒

Parse a beat-detection mode name (matches the Options-panel dropdown and the engine’s BeatDetectionMode::name()). Unknown values map to Off, which is also the engine’s boot default.

discover_presets 🔒

Discover preset files. Honours --preset first, then --preset-dir (one or more), then the default search path. Returns the list of .milk files found, in lexicographic order so the boot sequence is reproducible.

main 🔒

relaunch_self 🔒

Spawn a fresh copy of the current binary with the same CLI args and exit. Used by the Options panel’s “Apply & restart” button so settings that can’t be applied live (MSAA, texture format) take effect on the next boot. We rely on the caller having just called Settings::save() so the new process reads the user’s edits.
