-Calling Rust FFI libraries from Go
+Calling Rust FFI libraries from Go
+
+> Rust is an excellent systems language so it makes a lot of sense to be able to use Rust libraries in other languages. Rust supports a Foreign Function Interface (FFI) so you can call into other C libraries as well as allow C to call into Rust libraries.
+> 
+> Go has something similar with cgo, but we really don’t want to do anything with C directly. Memory safety is important, particularly for a security company! This means the ideal route is to write in Rust, but compile to a format that Go can interface with. That’s what FFI is for.
