Detailed Description

Represents a location in source code, similar to SourceContext but much more lightweight. SourceLocation does not take ownership of its given string, and assumes they are in static storage, which is the case for the file and function macros used below. But care has to be taken if one uses this class directly. The reason for this it so allow it to be fast, lightweight and constexpr. And to avoid unnecessary copies of file and function names. For a owning version
