data Criterion a

The monad in which most criterion code executes.

Instances

Monad Criterion

Methods

(>>=) :: Criterion a -> (a -> Criterion b) -> Criterion b

(>>) :: Criterion a -> Criterion b -> Criterion b

return :: a -> Criterion a

fail :: String -> Criterion a

Functor Criterion

Methods

fmap :: (a -> b) -> Criterion a -> Criterion b

(<$) :: a -> Criterion b -> Criterion a

Applicative Criterion

Methods

pure :: a -> Criterion a

(<*>) :: Criterion (a -> b) -> Criterion a -> Criterion b

(*>) :: Criterion a -> Criterion b -> Criterion b

(<*) :: Criterion a -> Criterion b -> Criterion a

MonadIO Criterion

Methods

liftIO :: IO a -> Criterion a

MonadReader Config Criterion

Methods

ask :: Criterion Config

local :: (Config -> Config) -> Criterion a -> Criterion a

reader :: (Config -> a) -> Criterion a

CritHPrintfType (Criterion a)

Methods

chPrintfImpl :: (Config -> Bool) -> PrintfCont -> Criterion a

withConfig :: Config -> Criterion a -> IO a

Run a Criterion action with the given Config.

getGen :: Criterion GenIO

Return a random number generator, creating one if necessary.

This is not currently thread-safe, but in a harmless way (we might call createSystemRandom more than once if multiple threads race).

getOverhead :: Criterion Double

Return an estimate of the measurement overhead.
