trait Tupler[A, B] extends AnyRef

Defines a strategy for tupling A and B values, according to types A and B.

The actual implementation avoids nested tuples and eliminates Unit, so that instead of ending with, e.g., the following type:

((Unit, Int), (((Unit, Unit), String)))

We just get:

(Int, String)

The following rules are implemented (by increasing priority):

  • A, B -> (A, B)
  • A, (B, C) -> (A, B, C)
  • (A, B), C -> (A, B, C)
  • (A, B), (C, D) -> (A, B, C, D)
  • A, Unit -> A
  • Unit, A -> A
