Module Set.String
Specalized when value type is string
, more efficient than the generic type, its compare behavior is fixed using the built-in comparison
This module is Belt.Set
specialized with value type to be a primitive type. It is more efficient in general, the API is the same with Belt.Set
except its value type is fixed, and identity is not needed(using the built-in one)
See Belt.Set
type value = string
The type of the set elements.
type t
The type of sets.
val empty : t
val fromArray : value array -> t
val fromSortedArrayUnsafe : value array -> t
val isEmpty : t -> bool
val has : t -> value -> bool
val add : t -> value -> t
add s x
If x
was already in s
, s
is returned unchanged.
val mergeMany : t -> value array -> t
val remove : t -> value -> t
remove m x
If x
was not in m
, m
is returned reference unchanged.
val removeMany : t -> value array -> t
val union : t -> t -> t
val intersect : t -> t -> t
val diff : t -> t -> t
val subset : t -> t -> bool
subset s1 s2
tests whether the set s1
is a subset of the set s2
.
val cmp : t -> t -> int
Total ordering between sets. Can be used as the ordering function for doing sets of sets.
val eq : t -> t -> bool
eq s1 s2
tests whether the sets s1
and s2
are equal, that is, contain equal elements.
val forEachU : t -> (value -> unit) Js.Fn.arity1 -> unit
val forEach : t -> (value -> unit) -> unit
forEach s f
applies f
in turn to all elements of s
. In increasing order
val reduceU : t -> 'a -> ('a -> value -> 'a) Js.Fn.arity2 -> 'a
val reduce : t -> 'a -> ('a -> value -> 'a) -> 'a
Iterate in increasing order.
val everyU : t -> (value -> bool) Js.Fn.arity1 -> bool
val every : t -> (value -> bool) -> bool
every p s
checks if all elements of the set satisfy the predicate p
. Order unspecified.
val someU : t -> (value -> bool) Js.Fn.arity1 -> bool
val some : t -> (value -> bool) -> bool
some p s
checks if at least one element of the set satisfies the predicate p
. Oder unspecified.
val keepU : t -> (value -> bool) Js.Fn.arity1 -> t
val keep : t -> (value -> bool) -> t
keep p s
returns the set of all elements in s
that satisfy predicate p
.
val partitionU : t -> (value -> bool) Js.Fn.arity1 -> t * t
val partition : t -> (value -> bool) -> t * t
partition p s
returns a pair of sets (s1, s2)
, where s1
is the set of all the elements of s
that satisfy the predicate p
, and s2
is the set of all the elements of s
that do not satisfy p
.
val size : t -> int
val toList : t -> value list
In increasing order
val toArray : t -> value array
val minimum : t -> value option
val minUndefined : t -> value Js.undefined
val maximum : t -> value option
val maxUndefined : t -> value Js.undefined
val get : t -> value -> value option
val getUndefined : t -> value -> value Js.undefined
val getExn : t -> value -> value
val split : t -> value -> (t * t) * bool
split x s
returns a triple (l, present, r)
, where l
is the set of elements of s
that are strictly less than x
; r
is the set of elements of s
that are strictly greater than x
; present
is false
if s
contains no element equal to x
, or true
if s
contains an element equal to x
.
val checkInvariantInternal : t -> unit
raise when invariant is not held
