A snapshot is created from a Vec<PathStat>> Getting a snapshot's contents returns a Vec<FileContent> There are two problems here: 1. Not all PathStats are files. So what should the relationship between the in Vec and out Vec be? Directories are skipped? Are empty? Are proto bytes? 2. Given a PathStat for a file contains its digest, why doesn't whatever just ask for a FileContent for a digest, rather than asking for all of the ones for a Snapshot? @salmon-summer-38098 @witty-crayon-22786
