Struct html5ever_stream::ParserFuture
[−]
[src]
#[must_use = "streams do nothing unless polled"]pub struct ParserFuture<S, C, E, D> where
D: TreeSink, { /* fields omitted */ }
ParserFuture takes in any stream that emits an item that can be referenced as a [u8]
It will collect the data from that stream into a html5ever parser. Currently you can't
control the parser, but eventually you will. The future resolves to a RcDom structure.
Examples
extern crate html5ever; extern crate hyper; extern crate html5ever_stream; extern crate futures; use futures::Future; use html5ever_stream::ParserFuture; use html5ever::rcdom::RcDom; use hyper::Body; const TEST_HTML: &'static str = "<html> <head> <title> test </title> </head> </html>"; let body: Body = TEST_HTML.into(); let dom = ParserFuture::new(body, RcDom::default()).wait().unwrap();
