index-set record (has private fields)

Set of nats. This takes up space proportional to the largest value.

list-new index-set(a nat32[])

to index-set(a nat32[])

move-to index-set(a mut-index-set)

any bool(a index-set)

size nat32(a index-set)

This is O(n) where 'n' is the result.

to nat32[](a index-set)

subscript bool(a index-set, index nat32)

~ index-set(a index-set, index nat32)

try-add index-set option(a index-set, index nat32)

~~ index-set(a index-set, indices nat32[])

- index-set(a index-set, index nat32)

try-remove index-set option(a index-set, index nat32)

count nat32(a index-set, range nat32 range)

Number of values in that are in both a and range.

count-greater-or-equal nat64(a index-set, n nat32)

Number of values in a that are >= n.

filter-less index-set(a index-set, limit nat32)

Gets the set with only values < limit

show string(a index-set)
