let has: t('value, 'id) => 'value => cmp:cmp('value, 'id) => bool;

let add: t('value, 'id) => 'value => cmp:cmp('value, 'id) => t('value, 'id);

add s x If x was already in s, s is returned unchanged.

  t('value, 'id) =>
  array('value) =>
  cmp:cmp('value, 'id) =>
  t('value, 'id);

let remove: t('value, 'id) => 'value => cmp:cmp('value, 'id) => t('value, 'id);

remove m x If x was not in m, m is returned reference unchanged.

let subset: t('value, 'id) => t('value, 'id) => cmp:cmp('value, 'id) => bool;

subset s1 s2 tests whether the set s1 is a subset of the set s2.

let cmp: t('value, 'id) => t('value, 'id) => cmp:cmp('value, 'id) => int;

Total ordering between sets. Can be used as the ordering function for doing sets of sets.

let eq: t('value, 'id) => t('value, 'id) => cmp:cmp('value, 'id) => bool;

eq s1 s2 tests whether the sets s1 and s2 are equal, that is, contain equal elements.

let forEachU: t('value, 'id) => Js.Fn.arity1(('value => unit)) => unit;

let forEach: t('value, 'id) => ('value => unit) => unit;

forEach s f applies f in turn to all elements of s. In increasing order

let reduceU: t('value, 'id) => 'a => Js.Fn.arity2(('a => 'value => 'a)) => 'a;

let reduce: t('value, 'id) => 'a => ('a => 'value => 'a) => 'a;

Iterate in increasing order.

let everyU: t('value, 'id) => Js.Fn.arity1(('value => bool)) => bool;

let every: t('value, 'id) => ('value => bool) => bool;

every p s checks if all elements of the set satisfy the predicate p. Order unspecified.

let someU: t('value, 'id) => Js.Fn.arity1(('value => bool)) => bool;

let some: t('value, 'id) => ('value => bool) => bool;

some p s checks if at least one element of the set satisfies the predicate p. Oder unspecified.

let keepU: t('value, 'id) => Js.Fn.arity1(('value => bool)) => t('value, 'id);

let keep: t('value, 'id) => ('value => bool) => t('value, 'id);

keep p s returns the set of all elements in s that satisfy predicate p.

let partitionU: 
  t('value, 'id) =>
  Js.Fn.arity1(('value => bool)) =>
  (t('value, 'id), t('value, 'id));

let partition: 
  t('value, 'id) =>
  ('value => bool) =>
  (t('value, 'id), t('value, 'id));

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.

let size: t('value, 'id) => int;

let toList: t('value, 'id) => list('value);

In increasing order

let toArray: t('value, 'id) => array('value);

let minimum: t('value, 'id) => option('value);

let minUndefined: t('value, 'id) => Js.undefined('value);

let maximum: t('value, 'id) => option('value);

let maxUndefined: t('value, 'id) => Js.undefined('value);

let get: t('value, 'id) => 'value => cmp:cmp('value, 'id) => option('value);

let getUndefined: 
  t('value, 'id) =>
  'value =>
  cmp:cmp('value, 'id) =>
  Js.undefined('value);

let getExn: t('value, 'id) => 'value => cmp:cmp('value, 'id) => 'value;

let split: 
  t('value, 'id) =>
  'value =>
  cmp:cmp('value, 'id) =>
  ((t('value, 'id), t('value, 'id)), 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.

let checkInvariantInternal: t(_, _) => unit;

raise when invariant is not held
