为serde_json设计的可怕宏

文档

类似于JavaScript风格的宏，用于轻松访问serde_json 值

#[macro_use] extern crate serde_wat;
extern crate serde_json;

use serde_json::from_str;
use serde_json::value::Value;

let a: Value = from_str(r#"{"b": {"c": 42}}"#).unwrap();
// Access unwrapping
assert_eq!(wat!(a.b.c as i64), 42);
// Safe access
assert_eq!(wat!(a.b as &str?), None);
// Testing
assert_eq!(wat!(a is bool), false);

示例

wat!(a.b.c as i64);
wat!(a as &mut Vec?);
wat!(a as &str);
wat!(a.b is i64);
wat!(a.b is &Map?);
wat!(a is &Map);
wat!(a.0 as bool);
