Rust low-level bindings for GMPMEE

The gmpmee-sys crate provides Rust FFI bindings to the GMP Modular Exponentiation Extension (GMPMEE), which is a minor extension of GMP. It adds simultaneous modular exponentiation and fixed base modular exponentiation functionality to the set of integer functions (the mpz-functions), as well as special purpose primality testing routines.

The crate is strongly inspired from gmp-mpfr-sys. In particular the file build.rs is copied from this crate, and adapted to the needs of the gmpmee-sys crate. No cache is implemented, since the compilation is quick.

Types

Unlike in the C libraries, the types (e.g. gmpmee_spowm_tab, gmpmee_fpowm_tab) are defined directly as structs, not as single-element arrays.

Using gmpmee-sys

The gmpmee-sys crate is available on crates.io. To use gmpmee-sys in your crate, add it as a dependency inside [Cargo.toml]:

[dependencies]
gmpmee-sys = "0.1"

Building on GNU/Linux

To build on GNU/Linux, simply make sure you have diffutils, gcc, make, autoconf, libtool, m4 and gmp installed on your system. For example on Debian:

sudo apt update 
sudo apt install diffutils gcc make m4 autoconf libtool libgmp3-dev

Building on macOS

To build on macOS, you need the command-line developer tools. To install them, run the following command in a terminal:

xcode-select --install

Building on Windows

Actually the crate is not working for Windows
