recv

If the channel is empty, not unbuffered, and not closed, blocks until there is a value in the channel.

If the channel is unbuffered, waits for a send operation.

Errors:

• ChannelError.CLOSED

If the channel has been closed and no more data.

Returns:

the result which holds a value if succeeded, or an error if failed.
