# performance-faster-string-find

Optimize calls to `std::string::find()` and friends when the needle passed is a single character string literal. The character literal overload is more efficient.

Examples:

    str.find("A");

    // becomes

    str.find('A');

## Options

`StringLikeClasses```

  Semicolon-separated list of names of string-like classes. By default only `std::basic_string` is considered. The list of methods to consired is fixed.
