void	AbslStringify (Sink &sink, const SourcePosition &p)

Detailed Description

A character position within some InputSources: a pair of line/column positions. Can only be interpreted in the context of some InputSources.

In files line numbering starts at 1, so 0 is reserved for "invalid" source positions. As a consequence, invalid source position are the "smallest", which is a reasonable choice.
