json-parser

JSON tokenizer and parser. JSON format supports following types:

Number, translates to Rust f68
String, translates to Rust owned String
Null, doesnt have a direct translation in Rust, indicates absence of value
Array, roughly tranlates to Vec<T>, where T is one of the listed types
Object, roughly translates to HashMap<String, T>, where T is one of the listed types

JSON value

is defined as follows:

pub enum Json {
 Null,
 Bool(bool),
 Number(f64),
 String(String),
 Array(Vec<Box<Json>>),
 Object(HashMap<String, Box<Json>>),
}

This enum implements FromStr trait and therefore can be used as follows:

let value: Json = json_string.parse::<Json>()?;

Add to your Cargo.toml
