weigh ![Tests](https://github.com/fpco/weigh/actions/workflows/tests.yml/badge.svg)
Measures the memory usage of a Haskell value or function
Limitations
- :warning: Turn off the
-threaded
flag, otherwise it will cause inconsistent results.
Example use
import Weigh
main :: IO ()
main =
mainWith
(do func "integers count 0" count 0
func "integers count 1" count 1
func "integers count 10" count 10
func "integers count 100" count 100)
where
count :: Integer -> ()
count 0 = ()
count a = count (a - 1)
Output results:
Case | Allocated | GCs |
---|---|---|
integers count 0 | 16 | 0 |
integers count 1 | 88 | 0 |
integers count 10 | 736 | 0 |
integers count 100 | 7,216 | 0 |
