Module rustc_mir_transform::coverage::spans

Modules

• from_mir 🔒

Structs

• BcbMapping 🔒
• CoverageSpan 🔒
  A BCB is deconstructed into one or more Spans. Each Span maps to a CoverageSpan that references the originating BCB and one or more MIR Statements and/or Terminators. Initially, the Spans come from the Statements and Terminators, but subsequent transforms can combine adjacent Spans and CoverageSpan from the same BCB, merging the merged_spans vectors, and the Spans to cover the extent of the combined Spans.
• CoverageSpans 🔒
• SpansRefiner 🔒
  Converts the initial set of CoverageSpans (one per MIR Statement or Terminator) into a minimal set of CoverageSpans, using the BCB CFG to determine where it is safe and useful to:

Enums

• BcbMappingKind 🔒

Functions

• generate_coverage_spans 🔒
  Extracts coverage-relevant spans from MIR, and associates them with their corresponding BCBs.
