Module Belt_SetString

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
