Minilib.Common.TimeEx
Defined in minilib-common@0.6.1
Timing module, such as sleep for a while, and measuring execution time.
Values
namespace Minilib.Common.TimeEx
consumed_realtime_while_io
Type: Std::IO a -> Std::IO (a, Std::F64)
Get wall-clock time elapsed while executing an I/O action.
measure_time
Type: Std::F64 -> (() -> a) -> Std::IO (Std::F64, a)
Measures wall-clock time per a function call. Specifically, It calls the function many times until the specified time limit (in second) passes and measures the total time. Returns the measured time per loop (in second) and the IO operation result. NOTE: The measured time per loop has a overhead about 0.1~1.0 usec.
measure_time_io
Type: Std::F64 -> Std::IO a -> Std::IO (Std::F64, a)
Measures wall-clock time per an IO operation. Specifically, It performs an IO operation many times until the specified time limit (in second) passes and measures the total time. Returns the measured time per loop (in second) and the IO operation result. NOTE: The measured time per loop has a overhead about 0.1~1.0 usec.
notimeit
Type: [a : Std::ToString] Std::String -> (() -> a) -> Std::IO a
Same interface as timeit() but does not measure time.
timeit
Type: [a : Std::ToString] Std::String -> (() -> a) -> Std::IO a
Measures wall-clock time per a function call. Specifically, It calls the function many times and measures the total time. It then prints the function result and measured time per loop. NOTE: The measured time per loop has a overhead about 0.1~1.0 usec. It is useful for measuring the performance of a function.
Parameters
label: a label for the function.f: a function to be measured.
Returns
- The result of the function.
timeit_io
Type: [a : Std::ToString] Std::String -> Std::IO a -> Std::IO a
Measures wall-clock time per an IO operation. Specifically, It performs an IO operation many times and measures the total time. It then prints the IO operation result and measured time per loop. NOTE: The measured time per loop has a overhead about 0.1~1.0 usec.
usleep
Type: Std::U32 -> Std::IO::IOFail ()
Sleeps for specified micro-seconds. For details, see Linux manual page for usleep().
