Detailed Description

What a stat and a directory entry both answer: the facts about one file, and no name.

The name is deliberately absent. A name buffer welded into this struct would set one length for every consumer, and the consumers do not agree: the SFTP codec sizes its entry scratch from what one NAME response must hold, WebDAV from an href, the RAM backend from its own file table. Each translation unit derives the length it needs and passes a buffer, so this type stays the four facts and carries no policy.

Stat and readdir share it because they answer the same question about the same directory record

• asking a backend for a size, then whether it is a directory, then its mtime is three lookups of one record, which on FAT is three seeks to learn what the first read already had.
