nyoom-json : json what goes nyoom

nyoom-json is a bare-bones streaming json generation library, built for specialized use cases and Just Going Fast :tm: it's also no-std!

credit where credit is due

nyoom-json borrows heavily in style from write-json, and takes its string escaping code from miniserde

examples

```rust use nyoom_json::{Serializer, Null}; let mut out = String::new(); let mut ser = Serializer::new(&mut out);

let mut obj = ser.object(); obj.field("kind", "cat"); obj.field("hasbeenfed", false); obj.field("meow_decibels", 45); obj.field("illness", Null); // good! mew :3 obj.end(); ```

```rust use nyoom_json::Serializer; let mut out = String::new(); let mut ser = Serializer::new(&mut out);

let mut arr = ser.array(); arr.add(1); arr.add(2); arr.add("three"); arr.end();

ser.end(); ```

```rust use nyoomjson::{Serializer, UnescapedStr}; let mut out = String::withcapacity(64); let mut ser = Serializer::new(&mut out); let mut arr = ser.array();

arr.addcomplex(|mut ser| { let mut state = ser.object(); state.field(UnescapedStr::create("mew"), 3); state.complexfield(UnescapedStr::create("meow"), |mut ser| { let mut seq = ser.array(); seq.add(3); seq.add(2); }); }); arr.add("ny"); arr.end(); ```
