file owner has these permissions

true if the file is a directory

true if only one client may have it open at a time

true if the file is a special authentication file

true if the file is temporary and should be skipped from nightly backups

A 'mode' returned from a call to "Stat"

The size of a buffer needed to hold t

val read : Cstruct.t -> ( t * Cstruct.t, [ `Msg of string ] ) Result.result

Read a t from the given buffer and return it, along with the unused remainder of the buffer. If the buffer cannot be parsed then return an error.

val write : t -> Cstruct.t -> ( Cstruct.t, [ `Msg of string ] ) Result.result

Write a t into the given buffer. If the buffer is too small, then return an error. Return the unused remainder of the buffer.
