19.  def inlineRequest(callsite: (callGraph)#Callsite, selectedRequestsForCallee: Set[InlineRequest]): Option[Either[OptimizerWarning, InlineRequest]]

    Returns the inline request for a callsite if the callsite should be inlined according to the current heuristics (`-Yopt-inline-heuristics`).

    The resulting inline request may contain post-inlining requests of callsites that in turn are also selected as individual inlining requests.

    returns

      `None` if this callsite should not be inlined according to the active heuristic `Some(Left)` if the callsite cannot be inlined (for example because that would cause an IllegalAccessError) but should be according to the heuristic TODO: what if a downstream inline request would cause an IAE and we don't create an InlineRequest for the original callsite? new subclass of OptimizerWarning. `Some(Right)` if the callsite should be and can be inlined

   Deprecated

     (Since version 2.12.16) Use `formatString.format(value)` instead of `value.formatted(formatString)`, or use the `f""` string interpolator. In Java 15 and later, `formatted` resolves to the new method in String which has reversed parameters.
