为json_in_type提供过程宏

此crate定义了一个derive模式宏，允许自动为自定义数据结构派生JSONValue trait。

示例

extern crate json_in_type;
#[macro_use]
extern crate json_in_type_derive;
use json_in_type::JSONValue;

#[derive(JSONValue)]
struct MyObject { // This will be encoded as a JSON object
    void: (),
    list: Vec<u8>,
    hello: String,
}

#[derive(JSONValue)]
struct WrapperStruct(u8, u8); // This will be encoded as a JSON list

lib.rs:

此模块提供了一个过程宏，用于为自定义结构体派生JSONValue。

示例

extern crate json_in_type;
#[macro_use] extern crate json_in_type_derive;
use json_in_type::JSONValue;

#[derive(JSONValue)]
struct MyObject {
    void: (),
    list: Vec<u8>,
    hello: String,
}

let obj = MyObject {
    void: (),
    list: vec![1, 2, 3],
    hello: String::from("world"),
};
assert_eq!(
    r#"{"void":null,"list":[1,2,3],"hello":"world"}"#,
    obj.to_json_string()
);
