type t

An abstract type for databases

type id = string
val init : string -> (t, [ `Msg of string ]) result

init path creates a database located at path path, which can be absolute or relative. If the path already exists, its contents is inspected to see if it looks like a bistro database; if not, a fresh database is created on the filesystem.

Returns an error message if path is occupied with something else than a bistro database.
