Inspectopedia 2025.2 Help

Simplifiable boolean union

Reports usages of true | false that can be replaced with bool. The bool keyword is a shorthand that aids readability.

A quick fix is available to convert any combination of true | false with bool.

Example:

# 'true | false' can be simplified type example = true | false

After the quick fix:

type example = bool
