This is a tiny crate with one purpose: generate temporary filenames from a hash of arbitrary data so that they are consistent across different crates. Its intended purpose is to either - give a consistent name, which can -- for example -- be used to cache the expensive output of an input across runs, - or to allow a caller to know what filename a different crate will have given some abstract data. It would be trivially easy to replicate; it exists primarily to allow consistency across otherwise unrelated crates when handling data
