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>()?;
