Crate oembed[−][src]
Expand description
This crate provides a simple generic implementation of the oEmbed specification version 1.0.
Notes and Caveats
- No HTTP client mechanism is included; users of this library must provide an
implementation of
client::Httpto functions requiring remote resources. - Discovery is not currently supported.
- XML responses are not currently supported.
- Some endpoints — not naming names — will return data that doesn’t conform with the specification; such data can’t currently be parsed by this library. No decision on how to address this has been made yet, and suggestions are welcome.
Examples
use std::error::Error;
use std::borrow::Cow;
use oembed::client::*;
struct DummyHttp;
impl Http for DummyHttp {
fn url_encode<'a>(&mut self, s: &'a str) -> HttpResult<Cow<'a, str>> {
Ok(s.into())
}
fn get(&mut self, _url: &str) -> HttpResult<String> {
Ok("{
