Dex – 1: Channels
Description: Reference for Dex-1: Channels

#### Channels

# Overview

`DexChannel` provides a producer consumer queue for applications. The channel has a read and a write side that allows you to put futures into the queue. Futures are used because they provide a convenient container that is used elsewhere in the library.

A common use of channels is to dispatch work to a worker fiber.

You can close the read or the write side independently which will cause the other side to be notified if waiting on a future.

Use `dex_channel_close_receive()` to close the read side of the channel. You should do this when stopping a worker fiber so that producers are notified that submitting items into the channel has failed.

Use `dex_channel_close_send()` to close the write side of the channel. This allows consumers to receive notification through the form of a rejection that reading from the channel will no longer succeed.
