Easy way to implement limit? about kotlinx-io HOT 4 CLOSED

I found that I need this feature as well in io-2. Current design gives fairly good idea how to use copy part of Input into new Input, but it seems not possible to make a zero-copy view of Input.

In new IO it's relatively easy to implement limit, though it won't be zero-copy (neither it can be by design)

It is quite easy to do with copy. I have a working example with input to output copy. But the idea is that you seldom need to limit how many bytes could be read and report preliminary EOF, and making complete input copy for that is an overkill. It is not hard to add manual limitation to the Input class, but I am not sure it is strictly necessary. For now workarounds seems rather elegant. I will write again if I hit real problem with this.

We're rebooting the kotlinx-io development (see #131), all issues related to the previous versions will be closed. Consider reopening it if the issue remains (or the feature is still missing) in a new version.
