Command Line Usage
Install the bindgen executable with cargo:
$ cargo install bindgen-cli
The bindgen executable is installed to ~/.cargo/bin. You have to add that
directory to your $PATH to use bindgen.
bindgen takes the path to an input C or C++ header file, and optionally an
output file path for the generated bindings. If the output file path is not
supplied, the bindings are printed to stdout.
If we wanted to generated Rust FFI bindings from a C header named input.h and
put them in the bindings.rs file, we would invoke bindgen like this:
$ bindgen input.h -o bindings.rs
For more details, pass the --help flag:
$ bindgen --help
