NAME
Bencher::Scenario::StringFunctions::Trim - Benchmark string trimming (removing whitespace at the start and end of string)
VERSION
This document describes version 0.003 of Bencher::Scenario::StringFunctions::Trim (from Perl distribution Bencher-Scenarios-StringFunctions), released on 2021-06-23.
SYNOPSIS
To run benchmark with default option:
% bencher -m StringFunctions::TrimTo run module startup overhead benchmark:
% bencher --module-startup -m StringFunctions::TrimFor more options (dump scenario, list/include/exclude/add participants, list/include/exclude/add datasets, etc), see bencher or run bencher --help.
DESCRIPTION
Packaging a benchmark script as a Bencher scenario makes it convenient to include/exclude/add participants/datasets (either via CLI or Perl code), send the result to a central repository, among others . See Bencher and bencher (CLI) for more details.
