You're seeing just the function
interval
, go back to Stream module for more information.
Specs
interval(timer()) :: Enumerable.t()
Creates a stream that emits a value after the given period n
in milliseconds.
The values emitted are an increasing counter starting at 0
.
This operation will block the caller by the given interval
every time a new element is streamed.
Do not use this function to generate a sequence of numbers.
If blocking the caller process is not necessary, use
Stream.iterate(0, & &1 + 1)
instead.
Examples

[0, 1, 2, 3, 4, 5, 6, 7, 8, 9]
