Thanks Timothy, that makes sense.
A follow on question if you don't mind.
I would like to 'take' n items off of a channel, but wait until n items are
available rather than eagerly returning the way take does. Do you have any
ideas on how
I could achieve this?
Hi,
I think by design core.async does not provide any information about the channel,
so there is no way to know how many items are available.
However I implemented something similar using the following. Where n
is the number of
items you want.
(repeatedly n #(!! feed-chan))
If the channel is closed with less than n items in it the remaining
items will be nil.
Note: I just started dabbling with core.async so there is probably a
better way to do this.
