Encoding with ard/encode

The ard/encode module provides a focused JSON encoder for primitive values. It exposes a small Encodable trait implemented only by the core primitives.

Note

Encodable is implemented by Str, Int, Float, and Bool. For structs, lists, maps, or Dynamic, use ard/json instead.

use ard/encode
use ard/io

fn main() {
  io::print(encode::json("hello").expect(""))  // "hello"
  io::print(encode::json(42).expect(""))       // 42
  io::print(encode::json(3.14).expect(""))     // 3.14
  io::print(encode::json(true).expect(""))     // true
}

API

trait Encodable

The trait required by the encoder. It is implemented only by the primitive types.

trait Encodable {
  fn to_dyn() Dynamic
}

fn json(value: Encodable) Str!Str

Encode a primitive value as a JSON string. Returns Ok with the JSON string or Err with an error message.

use ard/encode

let json = encode::json(200).expect("Failed to encode")
