class RuboCop::Cop::Performance::StringInclude
This cop identifies unnecessary use of a regex where `String#include?` would suffice.
This cop's offenses are not safe to auto-correct if a receiver is nil.
@example
# bad 'abc'.match?(/ab/) /ab/.match?('abc') 'abc' =~ /ab/ /ab/ =~ 'abc' 'abc'.match(/ab/) /ab/.match('abc') # good 'abc'.include?('ab')
