include Mirage_device.S with type 'a io = 'a Lwt.t
type 'a io = 'a Lwt.t
The type for potentially blocking I/O operation
type page_aligned_buffer = Cstruct.t
The type for memory buffers.
val read :
t ->
string ->
int64 ->
int64 ->
(page_aligned_buffer list, error) Pervasives.result io
read t key offset length
reads up to length
bytes from the value associated with key
. If less data is returned than requested, this indicates the end of the value.
val mem : t -> string -> (bool, error) Pervasives.result io
mem t key
returns true
if a value is set for key
in t
, and false
if not so.
val size : t -> string -> (int64, error) Pervasives.result io
Get the value size.
