Function toml::ser::to_string
[−]
[src]
pub fn to_string<T: ?Sized>(value: &T) -> Result<String, Error> where
T: Serialize,
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.
Examples
#[macro_use] extern crate serde_derive; extern crate toml; #[derive(Serialize)] struct Config { database: Database, } #[derive(Serialize)] struct Database { ip: String, port: Vec<u16>, connection_max: u32, enabled: bool, } fn main() { 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) }
