Small library for performing union, intersect, difference and distinct operations on slices in goLang. I don't promise that these are optimized (not even close!), but they work :).

QUESTION
I'm playing around with go generics by modifying a library I created for working with slices. I have a Difference
function which accepts slices and returns a list of unique elements only found in one of the slices.
I modified the function to use generics and I'm trying to write unit tests with different types (e.g. strings and ints) but am having trouble with the union type. Here's what I have, now:
...ANSWER
Answered 2021-Oct-29 at 19:33I've passed your code through gotip that uses a more evolved implementation of the proposal and it does not complain about that part of the code, so I would assume that the problem is with the go2go initial implementation.
Please note that your implementation will not work since you can definitely use parametric interfaces in type assertion expressions, but you can't use interfaces with type lists as you are doing in testDifference[intOrString]
QUESTION
While making my first approaches to using JMH
to benchmark my class, I encountered a behavior that confuses me, and I'd like to clarify the issue before moving on.
The situation that confuses me:
When I run the benchmarks while the CPU is loaded (78%-80%) by extraneous processes, the results shown by JMH
look quite plausible and stable:
ANSWER
Answered 2021-May-08 at 09:32The reason was very simple, and I should have understood it immediately. Power saving mode was enabled in the OS, which reduced the clock frequency of the CPU under low load. The moral is, always disable power saving when benchmarking!
