Neon-serde

This crate is a utility to easily convert values between

A Handle<JsValue> from the neon crate and any value implementing serde::{Serialize, Deserialize}

Usage

neon_serde::from_value

Convert a Handle<js::JsValue> to a type implementing serde::Deserialize

neon_serde::to_value

Convert a value implementing serde::Serialize to a Handle<JsValue>

Example

use serde::{Serialize, Deserialize};
use neon_serde2 as neon_serde;

use neon::prelude::*;

#[derive(Serialize, Debug, Deserialize)]
struct AnObject {
    a: u32,
    b: Vec<f64>,
    c: String,
}

fn deserialize_something(mut cx: FunctionContext) -> JsResult<JsValue> {
    let arg0 = cx.argument::<JsValue>(0)?;

    let arg0_value :AnObject = neon_serde::from_value(&mut cx, arg0)
        .or_else(|e| cx.throw_error(e.to_string()))
        .unwrap();
    println!("{:?}", arg0_value);

    Ok(JsUndefined::new(&mut cx).upcast())
}

fn serialize_something(mut cx: FunctionContext) -> JsResult<JsValue> {
    let value = AnObject {
        a: 1,
        b: vec![2f64, 3f64, 4f64],
        c: "a string".into()
    };

    let js_value = neon_serde::to_value(&mut cx, &value)
        .or_else(|e| cx.throw_error(e.to_string()))
        .unwrap();
    Ok(js_value)
}
