simple-json2
Simple JSON parser written with Rust. Wasm / no_std ready.
# Build this project in `no_std` env:
just build
# Running test in `no_std` env:

# Run this project in cli (a sample for parsing) in `std` env:
just run
Usage
To parse a string into JSON object
use simple_json2::{ self, parse_json, impls::SimpleError };
fn parse_simple() -> Result<(), SimpleError> {
let json_str = r#"{"data":{"id":"bitcoin","symbol":"BTC"},"timestamp":1574224303089}"#;
// To parse a string to JSON object
let json: JsonValue = parse_json(&json_str)?;
// To get a value out from the JSON object
let json_obj = &json.get_object()?[0];
// We use vec of char because in `no_std` env, there is no `String`
assert_eq!(json_obj.0, "data".chars().collect::<Vec<char>>());
let inner_obj = &json_obj.1.get_object()?[0];
assert_eq!(inner_obj.0, "id".chars().collect::<Vec<char>>());
// If we are in `std` env, we can retrieve value back as `String`
assert_eq!(inner_obj.1.get_string()?, "bitcoin");
// -- snip
}
