pub fn read_json () { let path = "./src/my_file.json"; let data = fs::read_to_string(path).expect("Unable to read file"); let obj: my_data = serde_json::from_str(&data).expect("Unable to parse"); println!("{:?}", obj); return } ...
In general, prefer to open issues against the main serde-rs/serde repository unless the topic is clearly specific to JSON. When reporting a bug or asking for help, please include enough details so that the people helping you can reproduce the behavior you are seeing. For some tips on how...
A string of JSON data can be parsed into a serde_json::Value by the serde_json::from_str function. There is also from_slice for parsing from a byte slice &[u8] and from_reader for parsing from any io::Read like a File or a TCP stream. use serde_json::{Result, Value}; fn ...

注意：如果json数据是一致的，那么可以使用适当的数据类型而不是字符串。
