Std.SortedMap.empty
1 declaration
fn
empty: fn(K, K) -> Bool -> Std.SortedMap.SortedMap[K, V]This is a callable function.
What it does
An empty map ordered by the given comparison.
The comparison answers whether its first key comes strictly before its
second. Strictly, because two keys that each come before the other are two
keys the order cannot tell apart, and this treats keys it cannot tell apart
as the same key.
