§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);
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}");

Structs§
- Parses a JSON file from a
&[u8]
. - Parses a JSON file from a

implementation. - A low-level JSON parser acting on a provided buffer.
- Result of
LowLevelJsonReader::read_next_event
. - A low-level JSON streaming writer writing to a
