Function toml::to_string

pub fn to_string<T>(value: &T) -> Result<String, Error>
where
    T: Serialize + ?Sized,

Serialize the given data structure as a String of TOML.

Serialization can fail if T’s implementation of Serialize decides to fail, if T contains a map with non-string keys, or if T attempts to serialize an unsupported datatype such as an enum, tuple, or tuple struct.

To serialize TOML values, instead of documents, see ValueSerializer.

Examples

use serde::Serialize;

#[derive(Serialize)]
struct Config {
    database: Database,
}

#[derive(Serialize)]
struct Database {
    ip: String,
    port: Vec<u16>,
    connection_max: u32,
    enabled: bool,
}

let config = Config {
    database: Database {
        ip: "192.168.1.1".to_string(),
        port: vec![8001, 8002, 8003],
        connection_max: 5000,
        enabled: false,
    },
};

let toml = toml::to_string(&config).unwrap();
println!("{}", toml)
