## ❗IMPORTANT❗
this crate has three features currently: `smol`, `async-std`, and
`tokio`.
You **must** enable one of these in order to use the crate. This
is intended to be a temporary situation, and eventually you will not
need to specify the runtime through feature flags.
## stability note
Please note that this crate is fairly incomplete, while functional. It
does not include any notion of range requests or cache headers. It
serves all files from disk every time, with no in-memory caching.
