Module spans

Modules§

compare_spans 🔒: Compares two spans in (lo ascending, hi descending) order.
discard_spans_overlapping_holes 🔒: Discard all covspans that overlap a hole.
ensure_non_empty_span 🔒
extract_refined_covspans 🔒
remove_unwanted_expansion_spans 🔒: Macros that expand into branches (e.g. assert!, trace!) tend to generate multiple condition/consequent blocks that have the span of the whole macro invocation, which is unhelpful. Keeping only the first such span seems to give better mappings, so remove the others.
remove_unwanted_overlapping_spans 🔒: Takes a list of sorted spans extracted from MIR, and “refines” those spans by removing spans that overlap in unwanted ways.
shrink_visible_macro_spans 🔒: When a span corresponds to a macro invocation that is visible from the function body, truncate it to just the macro name plus !. This seems to give better results for code that uses macros.
