weigh 
Measures the memory usage of a Haskell value or function
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 |
Output by default is plain text table; pass --markdown to get a
markdown output like the above.
