Rust + Golang
This repository shows how, by combining
cgo and
Rust's FFI capabilities, we can call
Rust code from Golang.
Run make build and then ./main to see Rust + Golang in action. You
should see Hello John Smith! printed to stdout.
You can do this for your own project
Begin by creating a lib directory, where you will keep your Rust libraries.
Andrew Oppenlander's article on creating a Rust dynamic library is a great introduction.
Then, you need to create a C header file for your library. Just copy the libc
types that you used.
All that is left to do is to add some cgo-specific comments to your Golang
code. These comments tell cgo where to find the library and its headers.
/*
#cgo LDFLAGS: -L./lib -lhello
#include "./lib/hello.h"
*/
import "C"
There should not be a newline between
*/andimport "C".
A simple make build (use the Makefile in this repository) will
result in a binary that loads your dynamic library.
