help about hello_world

[adjivas]

Hello,

I work with src/hello_world.rs file and try to use text::Text::new_color in my function but my prototype/code isn't valid:

Please, can you inform me about the good prototype to use for resolve my problem?

extern crate piston_window;
extern crate find_folder;

use piston_window::*;

fn draw<G: Graphics> (
    glyphs: &mut Glyphs,
    c: &Context,
    g: &mut G,
) {
    let transform = c.transform.trans(10.0, 100.0);

    text::Text::new_color([0.0, 1.0, 0.0, 1.0], 32).draw (
        "Hello world!",
        glyphs,
        &c.draw_state,
        transform, g
    );
}

fn main() {
    let window: PistonWindow = WindowSettings::new(
            "piston: hello_world",
            [200, 200]
        )
        .exit_on_esc(true)
        //.opengl(OpenGL::V2_1) // Set a different OpenGl version
        .build()
        .unwrap();

    let assets = find_folder::Search::ParentsThenKids(3, 3)
        .for_folder("assets").unwrap();
    println!("{:?}", assets);
    let ref font = assets.join("FiraSans-Regular.ttf");
    let factory = window.factory.borrow().clone();
    let mut glyphs = Glyphs::new(font, factory).unwrap();

    for e in window {
        e.draw_2d(|c, g| {
            draw(&mut glyphs, &c, g);
        });
    }
}
