Decomposing sets

These functions implements the Refine.DECOMPOSABLE interface. We cannot reference it here as Refine is implemented using bitsets, that would create a reference cycle.

Sourceval to_seq : t -> element Stdlib.Seq.t
Sourceval bind : t -> (element -> t) -> t
Sourceval split_by_run : (element -> element) -> t -> (element * t) list

Split a set into consecutive “runs” of elements that share the same class.

Parameters

  • cls : 'a element → 'b element that assigns a class to each element.
  • xs : 'a t – the input set to be split.

Returns A list of pairs. Each pair is made of a class (the result of cls for the run) and the subset of the original elements that belong to that run (preserving the original order).
