Like IdxSet, but with a hybrid representation: sparse when there are few
elements in the set, but dense when there are many. It's especially
efficient for sets that typically have a small number of elements, but a
large domain_size
, and are cleared frequently.

Create an error for a missing method specialization. Defaults to panicking with type, trait & method names. S
is the encoder/decoder state type, T
is the type being encoded/decoded, and the arguments are the names of the trait and method that should've been overridden. Read more
