Detailed Description

Warns when a local non trivial variable is unused within a function.

By default std::.*mutex and std::future are included.

The check supports these options:

• 'IncludeTypes': a semicolon-separated list of regular expressions matching types to ensure must be used.
• 'ExcludeTypes': a semicolon-separated list of regular expressions matching types that are excluded from the 'IncludeTypes' matches.
