std.data.json — JSON helpers

std.data.json (also exported as std.json) gives you explicit JSON parsing and conversion routines for working with Mux Json values.

• data.json.parse(string source) -> result<Json, string> — parses a JSON string.
• data.json.from_map(map<string, T>) -> result<Json, string> — converts a string-keyed map into a Json object (generic over values).
• data.json.to_map(Json value) -> result<map<string, Json>, string> — extracts an object map if the Json value is an object.

Example:

import std.data.json

func main() returns void {
    match json.parse("{\"user\": \"mux\"}") {
        ok(j) {
            match json.to_map(j) {
                ok(map) { print("user=" + map["user"].stringify(none).unwrap()) }
                err(e) { print("not object: " + e) }
            }
        }
        err(e) { print("parse failed: " + e) }
    }
}
