Crate corundum_framework 

corundum-framework — a single-dependency facade over the crates the sapphire apps and asteria share.

Depend on this one crate and turn on the features you need; each feature re-exports a corundum-framework-* crate as a module, the same way sapphire-framework’s facade does. The default is the part without egui, for the crates without a window (a server, a CLI); an app turns on gui.

# A desktop app:
corundum-framework = { version = "0.1", features = ["eframe", "serde"] }
# The same app on an Android phone:
corundum-framework = { version = "0.1", features = ["android", "serde"] }

Modules (feature-gated)

feature	module	crate
platform (default)	platform	corundum-framework-platform: the app’s directories, the system’s languages, the JNI / Objective-C bridging
gui	[gui]	corundum-framework-gui: the shell, theme, fonts, icons and translations (brings platform)
update	[update]	corundum-framework-update: finding newer GitHub releases of an app’s binary, and replacing it with one
self-update	update	update with the download and the replacement; a store build leaves it off, as the store updates the app
package	[package]	corundum-framework-package: the app as a Velopack package on the desktops: its start and install hooks, its updates, its command line on PATH and the Windows console shim (brings platform)
service	[service]	corundum-framework-service: the app’s background service registered with systemd, launchd or Task Scheduler at user level (brings platform)
keys	[keys]	corundum-framework-keys: API keys for an app’s server — a store of named keys, one file each, in a directory the app chooses, and their verification
keys-axum	keys::require_key	the layer that checks a router’s requests and resolves each key’s profile with the app’s function (brings keys)
keys-clap	keys::KeyCommand	the subcommand that manages a store; add --profile takes one of the app’s profiles (brings keys)
gui-keys	gui::keys	the API keys page in Settings, over a store on this machine or the app’s own backend; each key is added with one of the app’s profiles (brings gui and keys)
gui-update	gui::update	the gui crate’s update panel: the Settings → About rows that look for a newer release (brings gui and update)
gui-self-update	gui::update	the panel also downloads the release and replaces the running binary (brings gui-update and self-update)
gui-package	gui::update	the panel’s row for the app’s own Velopack package, Target::Package (brings gui-update and package)
gui-service	gui::first_run::ServicePage, gui::settings::ServiceRow	the gui crate’s service: the first-run question whether to keep the app’s services running, and an About-page row per service (brings gui, service and serde; desktops only)
eframe	gui::window::run, [eframe]	corundum-framework-gui with its eframe feature: a desktop window started the same way for every app
android	gui::window::run_android, [eframe]	corundum-framework-gui with its android feature: the window on an Android phone (brings eframe)
media-session	platform::media_session, gui::media_session	the OS’s media keys and its “now playing”, for a music player; gui::media_session::start makes one for an eframe window (brings platform). An iOS app adds UIBackgroundModes audio to its Info.plist
single-instance	platform::instance, gui::window::WindowOptions::single_instance	a desktop app run once: a second start brings the first’s window to the front and exits (brings platform)
console	platform::console	a Windows GUI-subsystem binary that also answers in a terminal without the package’s console shim: attach_parent on a command-line start, not the window’s (brings platform)
serde	gui::look, gui::store, gui::first_run	Serialize / Deserialize on the gui’s theme and language settings, and store: the look in effect and the rail’s order, kept on the device in a TOML file and put back before the first frame; first_run, the first-run pages, which remember there that they were done
