Function actix_web_lab::util::fork_request_payload

pub fn fork_request_payload(orig_payload: &mut Payload) -> Payload

Returns an effectively cloned payload that supports streaming efficiently.

The cloned payload:

• yields identical chunks;
• does not poll ahead of the original;
• does not poll significantly slower than the original;
• receives an error signal if the original errors, but details are opaque to the copy.

If the payload is forked in one of the extractors used in a handler, then the original must be read in another extractor or else the request will hang.
