adb is the Android CLI tool with which you can interact with your android device, from your PC
You must enable developer mode (tap 7 times on the build version in parameters) and install adb on your PC.
Don't hesitate to read comments, there is useful tips, thanks guys for this !

Pairings can be used for all kinds of advanced cryptographic schemes such as Encryption (Identity-based, Attribute-based, Predicate-based, etc.), Signatures, Zero-Knowledge Proofs, etc. It is in no particular order.
Provides multiple types of Elliptic Curve groups with appropriate pairings on top of them. Code repository resides here.

The following code is unsound:
This uses Rc::as_ref() to obtain a reference to the underlying data, which does not guarantee uniqueness. It is possible to obtain several mutable references to the same memory location by calling this function repeatedly:
let mycell = Cell::new(vec![1,2,3]);
