Usage

This gem is mainly useful for benchmarking code over a number of inputs. This input should be supplied in the form of an object capable of calling #each.

Sample benchmarking script:

require'benchmark/plot'classTestArrayattr_reader:arrdefinitializearr@arr=arrenddefto_s@arr.size.to_sendendtest_data=[5,25,50,75,100,125,150,175,200,250,300]test_data.map!{|e| TestArray.new(Array.new(e){|i| i})}Benchmark.plot(test_data)do |x|
x.report("map.flatten")do |data|
data.arr.map{[nil]}.flattenendx.report("flat_map")do |data|
data.arr.flat_map{[nil]}endend
