v/vlib/benchmark

Example usage of this module:

import benchmark
mut bmark := benchmark.new_benchmark()
// by default the benchmark will be verbose, i.e. it will include timing information
// if you want it to be silent, set bmark.verbose = false
for {
   bmark.step() // call this when you want to advance the benchmark.
                // The timing info in bmark.step_message will be measured starting from the last call to bmark.step
   ....

   //bmark.fail() // call this if the step failed
   //bmark.step_message(('failed')

   bmark.ok() // call this when the step succeeded
   println( bmark.step_message('ok')
}
bmark.stop() // call when you want to finalize the benchmark
println( bmark.total_message('remarks about the benchmark') )

benchmark.start() and b.measure() are convenience methods, intended to be used in combination. Their goal is to make benchmarking of small snippets of code as short, easy to write, and then to read and analyze the results, as possible. Example:

import benchmark
b := benchmark.start()

// your code 1 ...
b.measure('code_1')

// your code 2 ...
b.measure('code_2')

... which will produce on stdout something like this: SPENT 17 ms in code_1 SPENT 462 ms in code_2
