This is a standard module and does not need to be explicitly imported.

mut-set[t] record (has private fields)

Mutable unordered set.

list-new[t] t mut-set(a t[]) t key

is-empty[t] bool(a t mut-set) t key

size[t] nat64(a t mut-set) t key

to[t] t[](a t mut-set) t key

to[t] t set(a t mut-set) t key

to[t] t mut-set(a t[]) t key

to[t] t mut-set(a t set) t key

Copies an immutable set to a mutable set.

clear[t] void(a t mut-set) t key

Removes all elements.

move-to[t] t[](a t mut-set) t key

Returns an array of all elements in a. Afterwards, a will be empty.

move-to[t] t set(a t mut-set) t key

Returns a set equivalent to a. Afterwards, a will be empty.

~=[t] void(a t mut-set, value t) t key

Adds a value to the set. Does nothing if the value is already in the set.

~~=[t] void(a t mut-set, values t[]) t key

Adds many values. Like with ~=, values already in the set have no effect.

subscript[t] bool(a t mut-set, value t) t key

true if the set contains value.

try-add[t] bool(a t mut-set, value t) t key

If the value is already in the set, does nothing and returns false. Otherwise, adds it and returns true.

-=[t] void(a t mut-set, value t) t key

Same as remove but returning void

remove[t] bool(a t mut-set, value t) t key

If the value is in the set, removes it and returns true. Else, does nothing and returns false.

some[t] bool(a t mut-set, f bool mut(t)) t key
