feel free to close if its a duplicate, but i didnt see this filed anywhere

use serde::{Deserialize, Serialize};

#[derive(Serialize, Deserialize, Default)]
struct Hack(u32, String);

fn main() {
    let x = Hack::default();
    // works
    let y = toml::to_string(&x).unwrap();
    // fails
    let _: Hack = toml::from_str(&y).unwrap();
}

This is the repository for the TOML language, not any particular implementation. Looks like you want this instead: https://github.com/alexcrichton/toml-rs
