val size_header : t -> int

size_header t is t's header size.

val exists : string -> bool

exists name is true iff there is a pre-existing IO instance called name.

val size : t -> int

Returns the true size of the underlying data representation in bytes. Note that this is not necessarily equal to the total size of observable data, which is given by offset.
