libsodium-ffi

Rust native binding to libsodium

```toml

Cargo.toml

[dependencies] libsodium-ffi = "0.2" ```

Usage

Environement variables

• SODIUM_LIB_DIR=/path/to/libsodium for telling cargo where to find libsodium (Work with SODIUM_INCLUDE_DIR)

• SODIUM_INCLUDE_DIR=/path/to/libsodium/include for telling bindgen where to find libsodium's headers (Work with SODIUM_LIB_DIR)

• SODIUM_STATIC=yes for telling cargo to static-link libsodium

• SODIUM_BUILD_STATIC=yes force build from source instead of trying to find libsodium in system-wide

Examples

```bash

Specify paths by hand

This is the path to the directory of /usr/local/lib/libsodium.a

export SODIUMLIBDIR=/usr/local/lib

This is the path to the directory of /usr/local/include/sodium.h

export SODIUMINCLUDEDIR=/usr/local/include

Uses system-wide libsodium

Statically link system-wide libsodium

export SODIUM_STATIC=yes

Build libsodium from source

export SODIUMBUILDSTATIC=yes ```
