Crate rustpython

This is the rustpython binary. If you’re looking to embed RustPython into your application, you’re likely looking for the rustpython-vm crate.

You can install rustpython with cargo install rustpython, or if you’d like to inject your own native modules you can make a binary crate that depends on the rustpython crate (and probably rustpython-vm, too), and make a main.rs that looks like:

use rustpython_vm::{pymodule, py_freeze};
fn main() {
    rustpython::run(|vm| {
        vm.add_native_module("mymod".to_owned(), Box::new(mymod::make_module));
        vm.add_frozen(py_freeze!(source = "def foo(): pass", module_name = "otherthing"));
    });
}

#[pymodule]
mod mymod {
    use rustpython_vm::builtins::PyStrRef;

    #[pyfunction]
    fn do_thing(x: i32) -> i32 {
        x + 1
    }

    #[pyfunction]
    fn other_thing(s: PyStrRef) -> (String, usize) {
        let new_string = format!("hello from rust, {}!", s);
        let prev_len = s.as_str().len();
        (new_string, prev_len)
    }
}

The binary will have all the standard arguments of a python interpreter (including a REPL!) but it will have your modules loaded into the vm.

Re-exports

• pub use rustpython_vm as vm;

Structs

• InterpreterConfig
  The convenient way to create rustpython_vm::Interpreter with stdlib and other stuffs.

Enums

• RunMode

Functions

• opts_with_clap
• run
  The main cli of the rustpython interpreter. This function will return std::process::ExitCode based on the return code of the python code ran through the cli.
