class Benchmark::IPS::Report::Entry

Represents benchmarking code data for Report.

def body

Returns:
  • (String) - Left justified body. 
def body
  case Benchmark::IPS.options[:format]
  when :human
    left = "%s (±%4.1f%%) i/s" % [Helpers.scale(ips), stddev_percentage]
    iters = Helpers.scale(@iterations)
    if @show_total_time
      left.ljust(20) + (" - %s in %10.6fs" % [iters, runtime])

    end
  end
end

def display

Print entry to current standard output ($stdout). 
def display
  $stdout.puts to_s
end

def header

Returns:
  • (String) - Right justified header (+@label+). 
def header
  @label.to_s.rjust(20)
end

def initialize(label, us, iters, ips, ips_sd, cycles)

Parameters:
  • cycles (Integer) -- Number of Cycles.
  • ips_sd (Float) -- Standard deviation of iterations per second.
  • ips (Float) -- Iterations per second.
  • iters (Integer) -- Iterations.
  • us (Integer) -- Measured time in microsecond.
  • label (#to_s) -- Label of entry. 
def initialize(label, us, iters, ips, ips_sd, cycles)
  @label = label
  @microseconds = us
  @iterations = iters
  @ips = ips
  @ips_sd = ips_sd
  @measurement_cycle = cycles
  @show_total_time = false
end

def seconds

Returns:
  • (Float) - +@microseconds+ in seconds. 
def seconds
  @microseconds.to_f / 1_000_000.0
end

def show_total_time!

close to the expected time, so it's supressed by default.
Typically this value is not significant because it's very
Control if the total time the job took is reported. 
def show_total_time!
  @show_total_time = true
end

def stddev_percentage

Returns:
  • (Float) - +@ips_sd+ in percentage. 
def stddev_percentage
  100.0 * (@ips_sd.to_f / @ips.to_f)
end

def to_s

Returns:
  • (String) - Header and body. 
def to_s
  "#{header} #{body}"
