simple example of compiling rust

compilecompile.rs

extern crate rustc;
extern crate syntax;
use rustc::driver::config::{basic_options, build_configuration};
use rustc::driver::session::{build_session};
use rustc::driver::driver::{StrInput, compile_input};
use syntax::diagnostics;

fn main() {
    let src = "fn main() {println!(\"Awesome\");}";
    
    let opts = basic_options();
    let inp = StrInput(src.to_string());
    
    let descriptions = diagnostics::registry::Registry::new(rustc::DIAGNOSTICS);
    let sess = build_session(opts, None, descriptions);
    let cfg = build_configuration(&sess);
    
    compile_input(sess, cfg, &inp, &None, &None, None);
    println!("Hello, world!")
}
