They're very similar, but with very different ergonomics. Go channels are part of the language, so libraries use them frequently, whereas tokio is a separate library and not nearly as ubiquitous. So you'll get stuff like this:
This lets you implement a simple timeout for a channel read. So the barrier to using them is really low, so they get used a ton.
I haven't looked at the implementation of tokio channels, so I don't know if there's something subtly different, but they do have the same high level functionality.
