        format: Format,

}

What stands at an address in the tree.

Variants

Missing

No file is at this address; a save would create one.

Unreadable

Something is here and will not read - a directory, a file this process may not open - in the operating system’s own words.

Fields

reason: String

Empty

A file with no bytes. It has a version all the same, because an empty file is something a save can be made on.

Fields

version: B3Hash

format: Format

Held(Box<HeldDocument>)

A file with bytes.
