import Base

# PyTorch's wrap of a position among `limit` axes or elements (maybe_wrap_dim):
# a position d in -limit..limit-1 becomes d + limit when d is negative and d
# otherwise. A position outside that range stays outside it, at or past
# `limit`, so the operation refuses it with its own check, code and order:
# First{k} stays k, and an out-of-range Last{k} becomes `limit`.
def wrap(+limit: U32, position: Position) -> U32:
  match position:
    case First{k}:
      k
    case Last{+k}:
      Bool.pick(U32, U32.is_lt(k, limit), U32.sub(U32.sub(limit, 1), k), limit)
