Spans represent a region of code, used for error reporting. Positions in spans are absolute positions from the beginning of the source_map, not positions relative to SourceFiles. Methods on the SourceMap can be used to relate spans back to the original source. You must be careful if the span crosses more than one file - you will not be able to use many of the functions on spans in source_map and you cannot assume that the length of the span = hi - lo; there may be space in the BytePos range between files.
SpanData
is public because Span
uses a thread-local interner and can't be
sent to other threads, but some pieces of performance infra run in a separate thread.
Using Span
is generally preferred.
