serde

Serde is rust create used to serialize and deserialize stuff.

For example, this can be used to deserialize toml into a dedicated struct.

Example, with toml

Here is how serde after version 1.0 (included) should be used with serialize/deserialize mechanisms.

Be careful, there is breaking changes before version 1.0 and you can find confusing docs.

main.rs file

// uses
use serde::Deserialize;

[derive(Deserialize)]
struct Config {
    name: String,
    url: String,
}

fn main() {
    let content = r#"name = "example"
url = "https://example.com""#;

    let conf: Config = toml::from_str(content).unwrap();

    println!("name: {}, url: {}", conf.name, conf.url)

}

Cargo.toml file

[package]
name = "safiste"
version = "0.1.0"
authors = ["El Famoso Safiste"]
edition = "2018"

# See more keys and their definitions at https://doc.rust-lang.org/cargo/reference/manifest.html

[dependencies]
serde = { version = "1.0.94", features = ["derive"] }
toml = "0.5.1"

Output

name: example, url: https://example.com
