Rust Once, Run Everywhere

The Rust blog has posted a guide to using Rust's foreign function interface (FFI) with C code. Highlighted in particular are Rust's safe abstractions, which are said to impose no costs. "Most features in Rust tie into its core concept of ownership, and the FFI is no exception. When binding a C library in Rust you not only have the benefit of zero overhead, but you are also able to make it safer than C can! Bindings can leverage the ownership and borrowing principles in Rust to codify comments typically found in a C header about how its API should be used."
