[][src]Struct streamson_futures::stream::BufferStream

pub struct BufferStream<I> where
    I: Stream<Item = Bytes> + Unpin
{ /* fields omitted */ }

This struct is used to wrap Bytes input stream to (Path, Bytes) - the matched path and matched bytes in json stream

Examples


use bytes::Bytes;
use futures::stream::{self, StreamExt};
use streamson_lib::matcher;
use streamson_futures::stream::BufferStream;

let stream = stream::iter(
    vec![r#"{"users": ["#, r#"{"name": "carl", "id": 1}"#, r#"]}"#]
        .drain(..)
        .map(Bytes::from)
        .collect::<Vec<Bytes>>()
);
let matcher = matcher::Simple::new(r#"{"users"}[]{"name"}"#).unwrap();
let wrapped_stream = BufferStream::new(stream, Box::new(matcher));

Implementations

impl<I> BufferStream<I> where
    I: Stream<Item = Bytes> + Unpin
[src]

pub fn new(input: I, matcher: Box<dyn MatchMaker>) -> Self[src]

Wraps stream to extracts json paths defined by the matcher

Arguments

  • input - input stram to be matched
  • matcher - matcher which will be used for the extraction
