Interoperability

Rust has excellent support for interoperability with other languages. This means that you can:

• Call Rust functions from other languages.
• Call functions written in other languages from Rust.

When you call functions in a foreign language, you're using a foreign function interface, also known as FFI.

• This is a key ability of Rust: compiled code becomes indistinguishable from compiled C or C++ code.

• Technically, we say that Rust can be compiled to the same ABI (application binary interface) as C code.
