Tokio / Serde bindings for JSON

Utilities needed to easily implement a Tokio JSON transport using serde for JSON serialization and deserialization of frame values.

Documentation

Usage

To use tokio-serde-json, first add this to your Cargo.toml:

[dependencies]
tokio-serde-json = "0.2"

Next, add this to your crate:

extern crate tokio_serde_json;

use tokio_serde_json::{ReadJson, WriteJson};

lib.rs:

Stream and Sink adaptors for serializing and deserializing values using JSON.

This crate provides adaptors for going from a stream or sink of buffers (Bytes) to a stream or sink of values by performing JSON encoding or decoding. It is expected that each yielded buffer contains a single serialized JSON value. The specific strategy by which this is done is left up to the user. One option is to use using length_delimited from tokio-io.

Examples

use futures::prelude::*;

use serde_json::json;

use tokio::{codec::{FramedWrite, LengthDelimitedCodec}, net::TcpStream};

use tokio_serde_json::WriteJson;

#[tokio::main]
async fn main() {
    // Bind a server socket
    let socket = TcpStream::connect("127.0.0.1:17653")
        .await
        .unwrap();

    // Delimit frames using a length header
    let length_delimited = FramedWrite::new(socket, LengthDelimitedCodec::new());

    // Serialize frames with JSON
    let mut serialized = WriteJson::new(length_delimited);

    // Send the value
    serialized.send(json!({
      "name": "John Doe",
      "age": 43,
      "phones": [
        "+44 1234567",
        "+44 2345678"
      ]
    })).await.unwrap()
}
