Macros

app_version

The app’s own version: version= of apps/NAME/PACKAGE, which build_rs.py hands to rustc as JFGUI_VERSION (every program of the app); “0.0.0” without one. An expression of type &'static str: const APP_VERSION: &str = rt::app_version!();, update::Config::new(app, rt::app_version!(), ..).

main

(see above)

Constants

VERSION

the library’s version, “MAJOR.MINOR.PATCH” (the root Cargo.toml; docs/VERSIONING.md says what a change of each part promises). Not the app’s version: that is rt::app_version!().

VERSION_MAJOR

the first number of VERSION (incompatible API changes; while 0, the MINOR number counts them)

VERSION_MINOR

the second number of VERSION

VERSION_PATCH

the third number of VERSION

Functions

panic_hook

(feature std) std’s panics end as rt’s panic handler ends them without std: one line on stderr, the crash hook, exit code 3. plat’s start of a std program installs it; replacing it with std::panic::set_hook gives up JFLib’s crash report for panics.
