Struct FileCache 

pub struct FileCache<T> { /* private fields */ }

A bounded cache keyed by a file’s path and mtime.

A parsed message is expensive relative to everything else in a body request, and a maildir file never changes in place — a new message is a new file. Keying on mtime as well means the rare rewrite still invalidates.
