struct Ameba::Rule::Performance::AnyAfterFilter

Overview

This rule is used to identify usage of any? calls that follow filters.

For example, this is considered invalid:

[1, 2, 3].select { |e| e > 2 }.any?
[1, 2, 3].reject { |e| e >= 2 }.any?

And it should be written as this:

[1, 2, 3].any? { |e| e > 2 }
[1, 2, 3].any? { |e| e < 2 }

YAML configuration example:

Performance/AnyAfterFilter:
  Enabled: true
  FilterNames:
    - select
    - reject

Defined in:

ameba/rule/performance/any_after_filter.cr
