type t

An Epoll.Flags.t is an immutable set of flags for which one can register interest for a file descriptor. It is implemented as a bitmask, and so all operations (+, -, etc.) are constant time with no allocation.

sexp_of_t produces a human-readable list of bits, e.g. "(in out)".

val ascending : t -> t -> int

ascending is identical to compare. descending x y = ascending y x. These are intended to be mnemonic when used like List.sort ~cmp:ascending and List.sort ~cmp:descending, since they cause the list to be sorted in ascending or descending order, respectively.

val descending : t -> t -> int
val between : t -> low:t -> high:t -> bool
val clamp_exn : t -> min:t -> max:t -> t

clamp_exn t ~min ~max returns t', the closest value to t such that between t' ~low:min ~high:max is true.

Raises if not (min <= max).
