Function multistatus_stream_response_with_cancellation 

pub fn multistatus_stream_response_with_cancellation<S>(
    source: S,
    limits: DavMultiStatusLimits,
    cancellation: DavCancellationToken,

where
    S: Stream<Item = Result<DavMultiStatusItem, DavMultiStatusSourceError>> + Send + 'static,

Creates a streaming 207 response that cancels shared product work when its body is dropped.

Products should pass clones of cancellation to directory enumeration and property/lock preload operations. A transport-side client disconnect drops the response body and flips the same token, allowing those operations to stop at their next cancellation boundary.

Errors

Returns DavMultiStatusError when limits are invalid or response headers cannot be encoded.
