($launch:path) => { ... };
}Expand description
Declares the entry point an iOS application starts at.
iOS is the one platform where the application is the library: the renderer is a
Kotlin/Native archive and the two are linked into a single executable, so there is no
Activity to load anything and no page to fetch anything. What there is instead is a
main, and a main in an application bundle has to be C, so this exports the launch
under a name that C can call.
ⓘ
compose_rust::ios_main!(launch);The export exists only in a build for iOS. Anywhere else nothing calls it, and an unconditional export would collide with the same name in every other application linked into one binary, which is what a benchmark that drives several of them does.
