Expand description

Manages the counter and expression indexes/IDs to generate CoverageKind components for MIR Coverage statements.

Fields

function_source_hash: u64next_counter_id: u32num_expressions: u32debug_counters: DebugCounters

Implementations

Activate the DebugCounters data structures, to provide additional debug formatting features when formatting CoverageKind (counter) values.

Makes CoverageKind Counters and Expressions for the BasicCoverageBlocks directly or indirectly associated with CoverageSpans, and returns additional Expressions representing intermediate values.

Counter IDs start from one and go up.

Expression IDs start from u32::MAX and go down because an Expression can reference (add or subtract counts) of both Counter regions and Expression regions. The counter expression operand IDs must be unique across both types.
