Runtime configuration of a device

Sourceval create : ?id:string -> ?discard:bool -> ?keep_erased:int64 -> ?compact_after_unmaps:int64 -> ?check_on_connect:bool -> ?runtime_asserts:bool -> ?read_only:bool -> unit -> t

Customise the runtime behaviour, see connect or create

Sourceval to_string : t -> string

Marshal a config into a string suitable for a command-line argument

Sourceval of_string : string -> (t, [ `Msg of string ]) result

Parse the result of a previous to_string invocation
