JSON streaming parser

JSON event parser is a simple streaming JSON parser and serializer implementation in Rust.

It does not aims to be the fastest JSON parser possible but to be a simple implementation.

If you want fast and battle-tested code you might prefer to use json, serde_json or simd-json.

Reader example:

use json_event_parser::{FromReadJsonReader, JsonEvent};

let json = b"{\"foo\": 1}";
let mut reader = FromReadJsonReader::new(json.as_slice());
assert_eq!(reader.read_next_event()?, JsonEvent::StartObject);
assert_eq!(reader.read_next_event()?, JsonEvent::ObjectKey("foo".into()));
assert_eq!(reader.read_next_event()?, JsonEvent::Number("1".into()));
assert_eq!(reader.read_next_event()?, JsonEvent::EndObject);
assert_eq!(reader.read_next_event()?, JsonEvent::Eof);
# std::io::Result::Ok(())

Writer example:

use json_event_parser::{ToWriteJsonWriter, JsonEvent};

let mut writer = ToWriteJsonWriter::new(Vec::new());
writer.write_event(JsonEvent::StartObject)?;
writer.write_event(JsonEvent::ObjectKey("foo".into()))?;
writer.write_event(JsonEvent::Number("1".into()))?;
writer.write_event(JsonEvent::EndObject)?;

assert_eq!(writer.finish()?.as_slice(), b"{\"foo\":1}");
# std::io::Result::Ok(())
