Parse TOML in Rust by using the toml crate with serde to deserialize text into structs.

Use the toml crate to parse TOML files into Rust structs by defining a struct with #[derive(Deserialize)] and calling toml::from_str.

use serde::Deserialize;

#[derive(Deserialize)]
struct Config {
    name: String,
    version: u32,
}

fn main() {
    let toml_str = r#"
        name = "my-project"
        version = 1
    "#;
    let config: Config = toml::from_str(toml_str).unwrap();
    println!("{} v{}", config.name, config.version);
}
