# package `rr`, aka `RestartReader`

This package exists just to hold the `RestartReader` type. It wraps `io.ReadCloser` and implements it. It holds the data from every `Read` in a `[]byte` buffer, and allows you to call `.Restart()`, causing subsequent `Read` calls to start from the beginning again.

See [#140](https://github.com/makeworld-the-better-one/amfora/issues/140) for why this was needed.

Other projects are encouraged to copy this code if it's useful to them, and this package may move out of Amfora if I end up using it in multiple projects.
