a fork of serde_hjson.
The changes made to this crate are kept in CHANGELOG.
The Rust implementation of Hjson is based on the Serde JSON Serialization Library.
This crate is a Rust library for parsing and generating Human JSON Hjson. It is built upon Serde, a high performance generic serialization framework.
This crate works with Cargo and can be found on crates.io with a Cargo.toml
like:
[dependencies]
serde = "1"
nu-json = "0.76"
Add with:
cargo add serde
cargo add nu-json
extern crate serde;
extern crate nu_json;
use nu_json::{Map,Value};
fn main() {
// Now let's look at decoding Hjson data
let sample_text=r#"
{
# specify rate in requests/second
rate: 1000
array:
[
foo
bar
]
}"#;
// Decode and unwrap.
let mut sample: Map<String, Value> = nu_json::from_str(&sample_text).unwrap();
// scope to control lifetime of borrow
{
// Extract the rate
let rate = sample.get("rate").unwrap().as_f64().unwrap();
println!("rate: {}", rate);
// Extract the array
let array : &mut Vec<Value> = sample.get_mut("array").unwrap().as_array_mut().unwrap();
println!("first: {}", array.first().unwrap());
// Add a value
array.push(Value::String("baz".to_string()));
}
// Encode to Hjson
let sample2 = nu_json::to_string(&sample).unwrap();
println!("Hjson:\n{}", sample2);
}
At the moment, the documentation on serde_hjson / serde_json is also relevant for nu-json.
