Description
AUTHOR- Dr. Alistair Ward
DESCRIPTION- Determines the CPU-time, required to evaluate the specified pure expression.
Synopsis
- getCPUSeconds :: (Fractional seconds, NFData expression) => expression -> IO (seconds, expression)
- printCPUSeconds :: NFData expression => expression -> IO expression
Functions
Arguments
| :: (Fractional seconds, NFData expression) | |
| => expression | Arbitrary polymorphic expression. |
| -> IO (seconds, expression) | The original expression, tagged with the CPU-seconds taken. |
- Time the specified pure expression, returning the required number of CPU-seconds and the result, as a
Pair. - CAVEAT: as a side-effect, the expression is deep evaluated.
printCPUSeconds :: NFData expression => expression -> IO expression Source #
- Print the time required by the specified pure expression.
- CAVEAT: as a side-effect, the expression is deep evaluated.
