pjson.rs

A JSON stream parser for Rust.

This is a port of the pjson Go library.

It's designed to be very fast and use zero allocations.

Example

Print all string values from a JSON document.

```rust fn main() {

let json = br#"
{
  "name": {"first": "Tom", "last": "Anderson"},
  "age":37,
  "children": ["Sara","Alex","Jack"],
  "fav.movie": "Deer Hunter",
  "friends": [
    {"first": "Dale", "last": "Murphy", "age": 44, "nets": ["ig", "fb", "tw"]},
    {"first": "Roger", "last": "Craig", "age": 68, "nets": ["fb", "tw"]},
    {"first": "Jane", "last": "Murphy", "age": 47, "nets": ["ig", "tw"]}
  ]
}
"#;

pjson::parse(json, 0, |start: usize, end: usize, info: usize) i64 {
    if info&(pjson::STRING|pjson::VALUE) == pjson::STRING|pjson::VALUE {
        let el = String::from_utf8(json[start..end].to_vec()).unwrap();
        println!("{}", el);
    }
    1
});

}

// output: // "Tom" // "Anderson" // "Sara" // "Alex" // "Jack" // "Deer Hunter" // "Dale" // "Murphy" // "ig" // "fb" // "tw" // "Roger" // "Craig" // "fb" // "tw" // "Jane" // "Murphy" // "ig" // "tw" ```
