Expand description

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 CoverageStatement vectors, and the Spans to cover the extent of the combined Spans.

Note: A CoverageStatement merged into another CoverageSpan may come from a BasicBlock that is not part of the CoverageSpan bcb if the statement was included because it’s Span matches or is subsumed by the Span associated with this CoverageSpan, and it’s BasicBlock is_dominated_by() the BasicBlocks in this CoverageSpan.

Implementations

If the span is part of a macro, returns the macro name symbol.

If the span is part of a macro, and the macro is visible (expands directly to the given body_span), returns the macro name symbol.

Layout

Note: Most layout information is completely unstable and may even differ between compilations. The only exception is types with certain repr(...) attributes. Please see the Rust Reference’s “Type Layout” chapter for details on type layout guarantees.
