class Time

Represents a timing sample for benchmarking, including user, system, and real time.

Definitions

def self.measure

Measures the execution time of a block, returning a new class Sus::Fixtures::Benchmark::Time object with user, system, and real time.

Signature
returns　Time

The measured timing sample.

Implementation

 
def self.measure
	t0, r0 = Process.times, Process.clock_gettime(Process::CLOCK_MONOTONIC)
	yield
	t1, r1 = Process.times, Process.clock_gettime(Process::CLOCK_MONOTONIC)
	
	self.new(
		t1.utime  - t0.utime,
		t1.stime  - t0.stime,
		r1 - r0,
	)
end

def initialize(user = 0.0, system = 0.0, real = 0.0)

Initializes a new class Sus::Fixtures::Benchmark::Time object with user, system, and real time values.

Signature
parameter　user　Float

The user CPU time in seconds.

parameter　system　Float

The system CPU time in seconds.

parameter　real　Float

The real (wall clock) time in seconds.

Implementation

 
def initialize(user = 0.0, system = 0.0, real = 0.0)
	@user = user
	@system = system
	@real = real
end

attr :user

The user CPU time in seconds.

Signature
returns　Float

attr :system

The system CPU time in seconds.

Signature
returns　Float

attr :real

The real (wall clock) time in seconds.

Signature
returns　Float

def to_s

Returns a string representation of the real time in seconds.

Signature
returns　String

Implementation

 
def to_s
	"#{self.real}s"
end

def inspect

Returns a detailed string representation of the timing sample.

Signature
returns　String

Implementation

 
def inspect
	"#<#{self.class} user=#{self.user}s system=#{self.system}s real=#{self.real}s>"
end
