Module Epoll.Flags

type t

An Epoll.Flags.t is an immutable set of flags for which one can register interest in 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 sexp_of_t : t -> Ppx_sexp_conv_lib.Sexp.t
include Flags.S with type t := t
include Ppx_sexp_conv_lib.Sexpable.S with type t := t
val t_of_sexp : Sexplib0.Sexp.t -> t
val sexp_of_t : t -> Sexplib0.Sexp.t

consistent with subset

val (>=) : t -> t -> bool
val (<=) : t -> t -> bool
val (=) : t -> t -> bool
val (>) : t -> t -> bool
val (<) : t -> t -> bool
val (<>) : t -> t -> bool
val equal : t -> t -> bool
val compare : t -> t -> int

compare t1 t2 returns 0 if t1 is equal to t2, a negative integer if t1 is less than t2, and a positive integer if t1 is greater than t2.

val min : t -> t -> t
val max : t -> t -> t
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 ~compare: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

between t ~low ~high means low <= t <= high

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).

set union, bitwise or

val (-) : t -> t -> t

set difference. Although we use operators + and -, they do not satisfy the usual arithmetic equations, e.g. x - y = x + (empty - y) does not hold.

val intersect : t -> t -> t

bitwise and

val complement : t -> t

bitwise not

val is_empty : t -> bool
val do_intersect : t -> t -> bool
val are_disjoint : t -> t -> bool
val is_subset : t -> of_:t -> bool

is_subset t ~of_ is t = intersect t of_
