# modernize-min-max-use-initializer-list

Replaces nested `std::min` and `std::max` calls with an initializer list where applicable.

For instance, consider the following code:

    int a = std::max(std::max(i, j), k);

The check will transform the above code to:

    int a = std::max({i, j, k});

# Performance Considerations

While this check simplifies the code and makes it more readable, it may cause performance degradation for non-trivial types due to the need to copy objects into the initializer list.

To avoid this, it is recommended to use std::ref or std::cref for non-trivial types:

    std::string b = std::max({std::ref(i), std::ref(j), std::ref(k)});

# Options

IncludeStyle

  A string specifying which include-style is used, llvm or google. Default is llvm.

IgnoreNonTrivialTypes

  A boolean specifying whether to ignore non-trivial types. Default is true.

IgnoreTrivialTypesOfSizeAbove

  An integer specifying the size (in bytes) above which trivial types are ignored. Default is 32.
