Akka.NETSourceOperationsLimitWeightedT, TMat Method
Ensure stream boundedness by evaluating the cost of incoming elements using a cost function. Exactly how many elements will be allowed to travel downstream depends on the evaluated cost of each element. If the accumulated cost exceeds max, it will signal upstream failure StreamLimitReachedException downstream. Due to input buffering some elements may have been requested from upstream publishers that will then not be processed downstream of this step. The stream will be completed without producing any elements if max is zero or negative.

Emits when the specified number of elements to take has not yet been reached

Backpressures when downstream backpressures

Completes when the defined number of elements has been taken or upstream completes

Cancels when the defined number of elements has been taken or downstream cancels
