Measures the Time Elapsed by a Block

Here is how you can measure and log the time of a block:

require 'elapsed'
elapsed do
  run_something_slow
end

You can also send the log message to a log, for example to the Loog:

require 'elapsed'
require 'loog'
elapsed(Loog::VERBOSE) do
  # any code
end

You can also make the message custom:

elapsed(good: 'File saved') do
  File.save(f, 'Hello, world!')
end

Or, you can make the message even more custom:

elapsed do
  File.save(f, 'Hello, world!')
  throw :"Successfully saved #{File.size(f)} bytes"
end

You can also filter out small durations using the over: parameter:

elapsed(Loog::VERBOSE, over: 0.5) do
  # This message will only be logged if the block takes more than 0.5 seconds
  run_something_that_might_be_fast
end

That's it.
