Streamson Lib

Rust library to split large JSONs.

It doesn't actually perform the parsing. It just splits JSONs. And triggers handlers on matched paths.o

Note that it doesn't fully validates whether the JSON is valid. This means that invalid JSONs might pass without an error.

Examples

Simple

use streamson_lib::{Collector, GenericError, PrintLn, Simple};

let mut collector = Collector::new();
let handler = Arc::new(Mutex::new(PrintLn::new());
let matcher = Simple(r#"{"users"}[]"#);
collector = collector.add_matcher(Box::new(matcher), &[handler]);

let mut buffer = [0; 2048];
while let Ok(size) = input.read(&mut buffer[..]) {
	collector.process(&buffer[..size]);
}

Traits

Custom Handlers

You can define your custom handler.

use streamson_lib::handler;

...

struct CustomHandler;

impl handler::Handler for CustomHandler {
	...
}

Custom Matchers

You can define custom matchers as well.

use streamson_lib::matcher;

struct CustomMatcher;

impl matcher::MatchMaker for CustomMatcher {
	...
}
