Strict JSON parsing and mapping library

This library provides a strict JSON parser as defined by RFC 8259 and ECMA-404. It is built on the locspan library so as to keep track of the position of each JSON value in the parsed document.

Features

• Strict implementation of RFC 8259 and ECMA-404.
• No stack overflow, your memory is the limit.
• Numbers are stored in lexical form thanks to the json-number crate, their precision is not limited.
• Duplicate values are preserved. A JSON object is just a list of entries, in the order of definition.
• Strings are stored on the stack whenever possible, thanks to the smallstr crate.
• The parser is configurable to accept documents that do not strictly adhere to the standard.
• Highly configurable printing methods.
• Macro to build any value statically.
• JSON Canonicalization Scheme implementation (RFC 8785) enabled with the canonicalization feature.
• serde support (by enabling the serde feature).
• Thoroughly tested.

Usage

use std::fs;
use json_syntax::{Value, Parse, Print};

let filename = "tests/inputs/y_structure_500_nested_arrays.json";
let input = fs::read_to_string(filename).unwrap();
let mut value = Value::parse_str(&input, |span| span).expect("parse error");
println!("value: {}", value.pretty_print());
