Function btree_set
fn btree_set<T: Strategy, impl Into<SizeRange>: Into<SizeRange>>(element: T, size: impl Into<SizeRange>) -> BTreeSetStrategy<T>
where
<T as >::Value: Ord
Create a strategy to generate BTreeSets containing elements drawn from
element and with a size range given by size.
This strategy will implicitly do local rejects to ensure that the
BTreeSet has at least the minimum number of elements, in case element
should produce duplicate values.
