type t

An instance of t represents the identity of the contents of a file path. Use this to quickly detect if a file has changed. (Detection is done by checking some fields from stat syscall, it can be tricked but should behave well in regular cases). FIXME: precision of mtime is still the second?!

val check : t -> t -> bool

Returns true iff the heuristic determines that the file contents has not changed.

val get : string -> t

file_id filename computes an id for the current contents of filename

val with_cache : (unit -> 'a) -> 'a
