Crate cranpose_capabilities 

What an application asks of the device it runs on, written once in Rust.

An application declares this in its build script:

use cranpose_capabilities::{Use, declare};

declare(&[
    Use::camera("Reads a receipt with the camera. Nothing leaves this device."),
    Use::notifications(),
])
.opening(&["image/*", "application/pdf"])
.emit();

From that one list the build writes the Android permissions and feature declarations, the Android intent filters that offer the application for the files it opens, the Apple usage descriptions, and a constant the application itself reads at run time. A service is a function, so a name cannot be misspelled, and a service Apple wants a sentence for takes that sentence as an argument, so it cannot be forgotten.
