produce
produce(value)
Send the given value to the last consume
call, switching to the consumer task. If the next consume
call passes any values, they are returned by produce
.
Examples
-
Send a value to the consumer task:
julia> produce(10) 10
This example sends the value
10
to the consumer task. It will be returned by the nextconsume
call. -
Use with consume to communicate between tasks:
julia> task_consumer() = begin value = consume() println("Received value: $value") end; julia> @async task_consumer(); julia> produce("Hello, Julia!") Received value: Hello, Julia!
Here,
produce
is used in conjunction withconsume
to communicate between tasks. The consumer tasktask_consumer
waits for a value fromconsume
and prints it out. -
Handle multiple values returned by
consume
:julia> task_consumer() = begin value1, value2 = consume(), consume() println("Received values: $value1, $value2") end; julia> @async task_consumer(); julia> produce(42) julia> produce("Julia") Received values: 42, Julia
In this example, the consumer task expects two values from
consume
.produce
is called twice to send the values, and they are printed by the consumer task.
Common mistake example:
julia> produce()
ERROR: MethodError: no method matching produce()
In this example, produce
is called without providing a value. It's important to provide a value to produce
as it is required to pass to the next consume
call.
