Function actix_web_lab::util::fork_request_payload
source ยท pub fn fork_request_payload(orig_payload: &mut Payload) -> Payload
Expand description
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.
