/*!
# Trillium handlers for etag and last-modified-since headers.

This crate provides three handlers: [`Etag`], [`Modified`], and
[`CachingHeaders`], as well as a [`CachingHeadersExt`] that extends
[`trillium::Headers`] with some accessors.

Unless you are sure that you _don't_ want either etag or last-modified
behavior, please use the combined [`CachingHeaders`] handler.
