Expand description

Handle resource URLs.

See DispatchingResourceHandler for a resource handler which dispatches to a list of handlers, and FileResourceHandler for a resource handler for local files.

For remote URLs implement this handler on top of a suitable crate for network requests, e.q. reqwest or curl.

Required Methods§

fn read_resource(&self, url: &Url) -> Result<MimeData>

Read a resource.

Read data from the given url, and return the data and its associated mime type if known, or any IO error which occurred while reading from the resource.

Alternatively, return an IO error with ErrorKind::Unsupported to indicate that the given url is not supported by this resource handler. In this case a higher level resource handler may try a different handler.
