// From the serde_json docs:
|

//
|
||||
// > There are three common ways that you might find yourself needing to work with
|
||||
// > JSON data in Rust.
|
||||
// >
|
||||
// > 1. As text data. An unprocessed string of JSON data that you receive on an
|
||||
// > HTTP endpoint, read from a file, or prepare to send to a remote server.
|
||||
// > 2. As an untyped or loosely typed representation. Maybe you want to check
|
||||
// > that some JSON data is valid before passing it on, but without knowing
|
||||
// > the structure of what it contains. Or you want to do very basic
|
||||
// > manipulations like insert a key in a particular spot.
|
||||
// > 3. As a strongly typed Rust data structure. When you expect all or most of
|
||||
// > your data to conform to a particular structure and want to get real work
|
||||
// > done without JSON’s loosey-goosey nature tripping you up.
|
||||
//
|
||||
// So let's take a look at all three...
|
||||
|
||||
// 1) Reading/writing from/to plain text.
|
||||
// TL;DR:
|
||||
// - read: serde_json::from_str(data)
|
||||
// - write: x.to_string()

let data = json!({

"fname": "William",
|

"lname": "Carroll",
|

"age": 30,

})

.to_string();
|

println!("result: {:?}", data);
