Class: RuboCop::Cop::Style::HashTransformValues
- Includes:
- HashTransformMethod
- Defined in:
- lib/rubocop/cop/style/hash_transform_values.rb
Overview
This cop looks for uses of ‘_.each_with_object({}) …`, `_.map ….to_h`, and `Hash[_.map …]` that are actually just transforming the values of a hash, and tries to use a simpler & faster call to `transform_values` instead.
This can produce false positives if we are transforming an enumerable of key-value-like pairs that isn’t actually a hash, e.g.: ‘[[k1, v1], [k2, v2], …]`
This cop should only be enabled on Ruby version 2.4 or newer (‘transform_values` was added in Ruby 2.4.)
