Class: RuboCop::Cop::Style::HashExcept
- Extended by:
- AutoCorrector, TargetRubyVersion
- Includes:
- HashSubset
- Defined in:
- lib/rubocop/cop/style/hash_except.rb
Overview
Checks for usages of ‘Hash#reject`, `Hash#select`, and `Hash#filter` methods that can be replaced with `Hash#except` method.
This cop should only be enabled on Ruby version 3.0 or higher. (‘Hash#except` was added in Ruby 3.0.)
For safe detection, it is limited to commonly used string and symbol comparisons when using ‘==` or `!=`.
This cop doesn’t check for ‘Hash#delete_if` and `Hash#keep_if` because they modify the receiver.
