NOTE: Updated to Rust 2018

NOTE: This version of the library requires Version 1.31+ of Rust for 64-bit 
integer support and for Rust 2018. 

Now AMCL version 3 is distributed as a cargo crate.

Namespaces are used to separate different curves.

To build the library and see it in action, copy all of the files in this 
directory and its subdirectories to a fresh root directory. 

Then for example execute

cargo rustc  --release --features "bn254 bls383 bls24 bls48 ed25519 nist256 goldilocks rsa2048"

This will create a build of the library for the current default target (be it 32 or 64 bits). 

(To test a 32-bit environment you can follow the Web Assembly (wasm) readme instructions for rust)

Next copy the library from target/release/libamcl.rlib into the root 
directory and execute

rustc TestALL.rs --extern amcl=libamcl.rlib

rustc TestBLS.rs --extern amcl=libamcl.rlib

rustc BenchtestALL.rs --extern amcl=libamcl.rlib

rustc TestNHS.rs --extern amcl=libamcl.rlib

Finally execute these programs.

To add amcl functionality to your own programs, add a dependency to your 
Cargo.toml file. For example to use the curve bls48, add this dependency

[dependencies]

amcl = { version = "0.2.0",  optional = true, default-features = false, features = ["bls48"]}

if published to crates.io, or 

amcl = { version = "0.2.0",  optional = true, default-features = false, features = ["bls48"], path="your_amcl_location" }

And to use primitives of the needed curve in your source code:

use amcl::bls48::{ECP, ECP8}; //any primitive you need
