Sender

A Sender is used to send values into a channel. Senders are sinks, used with put or the .put() method.

Inherits

• Sink

Creating a Sender

Senders are created by the channel function:

let send recv = channel()
let send recv = channel 10  # buffered channel

Using a Sender

Send values using put or .put():

send.put 42
send.put "hello"

Methods

close error? :backtrace?

Closes the sender, signaling EOF to receivers. After closing:

• Sends will fail
• Receivers will eventually see no more values
• If error is provided, the receiver re-raises it from .next() once any buffered values have been drained

Parameters

Name	Type	Description
error		Optional error value to propagate
backtrace	strand.Backtrace?	Optional backtrace for that error

send.close()
send.close "boom"

Example

let send recv = channel()

fork
  do
    send.put 1
    send.put 2
    send.put 3
    send.close()
  do for value = recv
    echo $value
