68/// Declares the entry point an iOS application starts at.
69///
70/// iOS is the one platform where the application is the library: the renderer is a
71/// Kotlin/Native archive and the two are linked into a single executable, so there is no
72/// Activity to load anything and no page to fetch anything. What there is instead is a
73/// `main`, and a `main` in an application bundle has to be C, so this exports the launch
74/// under a name that C can call.
75///
76/// ```ignore
77/// compose_rust::ios_main!(launch);
78/// ```
79///
80/// The export exists only in a build for iOS. Anywhere else nothing calls it, and an
81/// unconditional export would collide with the same name in every other application
82/// linked into one binary, which is what a benchmark that drives several of them does.
