Core benchmarking code.

Synopsis

class Benchmarkable b where run :: b -> Int -> IO () data Benchmark bench :: Benchmarkable b => String -> b -> Benchmark bgroup :: String -> [Benchmark] -> Benchmark runBenchmark :: Benchmarkable b => Environment -> b -> ConfigM Sample runAndAnalyse :: (String -> Bool) -> Environment -> Benchmark -> ConfigM ()

Documentation

class Benchmarkable b where Source

A benchmarkable function or action. Methods run :: b -> Int -> IO () Source Instances Benchmarkable (IO a) Benchmarkable (Int -> a)

data Benchmark Source

A benchmark may consist of either a single Benchmarkable item with a name, created with bench, or a (possibly nested) group of Benchmarks, created with bgroup. Instances Show Benchmark

bench Source

:: Benchmarkable b => String -> b -> Benchmark Create a single benchmark.

bgroup Source

:: String A name to identify the group of benchmarks. -> [Benchmark] Benchmarks to group under this name. -> Benchmark Group several benchmarks together under a common name.

runBenchmark :: Benchmarkable b => Environment -> b -> ConfigM Sample Source

Run a single benchmark, and return timings measured when executing it.

runAndAnalyse Source

:: String -> Bool A predicate that chooses whether to run a benchmark by its name. -> Environment -> Benchmark -> ConfigM () Run, and analyse, one or more benchmarks.
