The Lwt variation of Cachet implies a point of cooperation (Lwt.pause) as soon as the syscall map is called. In other words, a task developed with Cachet_lwt will make itself available to be rescheduled if we internally call map instead of using the cache.

In the event that the functions below were to use the cache, they would retain the exclusive right to execute and would not allow any cooperation points to appear.

Such an approach increases the task's availability if it does I/O in cooperation with other tasks that would also like to do I/O.

val load : 'fd Cachet.t -> ?len:int -> int -> Cachet.slice option Lwt.t

val get_int8 : 'fd Cachet.t -> int -> int Lwt.t

get_int8 t logical_address is t's signed 8-bit integer starting at byte index logical_address.

raises Out_of_bounds
if logical_address is not accessible.

val get_uint8 : 'fd Cachet.t -> int -> int Lwt.t

get_uint8 t logical_address is t's unsigned 8-bit integer starting at byte index logical_address.

raises Out_of_bounds
if logical_address is not accessible.
