Readme for microtimer-

[back to package description]

A tiny Haskell library for timing IO actions.

Build Status

This package contains a very simple module for benchmarking IO actions. It was taken from criterion.

The API simply provides:

-- | Time an 'IO' action and return the time taken for execution,
-- as well as the return value.
time :: IO a -> IO (Double, a)

-- | Time an 'IO' action, throwing away the result and returning
-- the time taken for execution.
time_ :: IO a -> IO Double

-- | Convert a 'Double' value into a 'String' which specifies
-- how long something took in seconds.
formatSeconds :: Double -> String


It's just a cabal install away on Hackage:

$ cabal install microtimer
