func SortedKeys ¶

func SortedKeys[V any](m map[string]V) []string

SortedKeys returns the keys of a map sorted alphabetically.

An empty or nil map yields an empty slice rather than a nil one, so a caller that serializes the result writes an empty list and not a null.

Not slices.Sorted(maps.Keys(m)): that grows without a size hint, measured at 3 to 15 allocations against 1 here, and this has callers on the walk and generate paths.
