Crust of Rust: Build Scripts and Foreign-Function Interfaces (FFI)
This time we go over Cargo build scripts and Rust foreign-function interfaces, including looking at some widely used *-sys crates. We also wrote our own bindings against the libsodium C library: https://doc.libsodium.org/. You can find the Cargo book entry for build scripts at https://doc.rust-lang.org/cargo/refer..., and the nomicon entry for ffi at https://doc.rust-lang.org/nomicon/ffi....
