consume

consume(task, values...)

Receive the next value passed to produce by the specified task. Additional arguments may be passed, to be returned from the last produce call in the producer.

Examples

  1. Consume values from a producer task:

    julia> function producer()
              produce("apple")
              produce("banana")
              produce("orange")
          end
    
    julia> task = Task(producer)
    julia> consume(task)  # Consume the next value
    "apple"
    julia> consume(task)  # Consume the next value
    "banana"

    In this example, the consume function is used to retrieve the next value produced by the producer task.

  2. Consume values with additional arguments:

    julia> function producer()
              produce("apple")
              produce("banana")
              produce("orange")
          end
    
    julia> task = Task(producer)
    julia> consume(task, "additional", "arguments")  # Consume the next value with additional arguments
    "apple"

    The consume function can also accept additional arguments, which will be returned from the last produce call in the producer.

  3. Handle multiple producer tasks:

    julia> function producer1()
              produce("apple")
          end
    
    julia> function producer2()
              produce("banana")
          end
    
    julia> task1 = Task(producer1)
    julia> task2 = Task(producer2)
    julia> consume(task1)  # Consume value from task1
    "apple"
    julia> consume(task2)  # Consume value from task2
    "banana"

    This example demonstrates how to handle multiple producer tasks and consume values from each task separately.

Common mistake example:

julia> function producer()
           produce("apple")
           produce("banana")
       end

julia> task = Task(producer)
julia> consume(task, "additional", "arguments")  # Consume the next value with additional arguments
ERROR: MethodError: no method matching consume(::Task, ::String, ::String)

In this example, the consume function is mistakenly called with additional arguments, but the consume function does not accept any additional arguments. Make sure to only pass the necessary arguments to the consume function as per its definition.
