Crate wolf_span 

Source files, positions and ranges.

Every file the compiler reads is stored once in a SourceMap and identified by a FileId. Positions inside a file are byte offsets (Span). Line and column numbers are computed only when a diagnostic is shown; columns count Unicode scalar values (spec chapter 1, section 1).
