muon-rs

A Rust library for the MuON data format, using serde.

See documentation for more information.

Deserializing

The easiest way to deserialize data is to derive serde::Deserialize on a struct. Then use one of the from_ functions.

Example

MuON file:

book: Pale Fire
  author: Vladimir Nabokov
  year: 1962
  character: John Shade
    location: New Wye
  character: Charles Kinbote
    location: Zembla
book: The Curious Incident of the Dog in the Night-Time
  author: Mark Haddon
  year: 2003
  character: Christopher Boone
    location: Swindon
  character: Siobhan

Rust code:

#[derive(Debug, Deserialize, Serialize)]
struct BookList {
    book: Vec<Book>,
}

#[derive(Debug, Deserialize, Serialize)]
struct Book {
    title: String,
    author: String,
    year: Option<i16>,
    character: Vec<Character>,
}

#[derive(Debug, Deserialize, Serialize)]
struct Character {
    name: String,
    location: Option<String>,
}

let muon = File::open("tests/books.muon")?;
let books: BookList = muon_rs::from_reader(muon)?;
println!("{:?}", books);

Serializing

Deriving serde::Serialize on a struct is just as easy. The to_ functions are used to serialize MuON data.

Example

let books = BookList {
    book: vec![
        Book {
            title: "Flight".to_string(),
            author: "Sherman Alexie".to_string(),
            year: Some(2007),
            character: vec![
                Character {
                    name: "Zits".to_string(),
                    location: Some("Seattle".to_string()),
                },
                Character {
                    name: "Justice".to_string(),
                    location: None,
                },
            ],
        },
    ],
};
let muon = muon_rs::to_string(&books)?;
println!("{:?}", muon);

Types

MuON types can be mapped to different Rust types.

MuON Type	Rust Types

int	i8  i16  i32  i64  i128  isize  u8  u16  u32  u64  u128  usize
number	f32  f64
datetime	DateTime
date	Date
time	Time
record	struct implementing Deserialize
dictionary	HashMap
any	Value
