Function sibling_out_edge_targets

fn sibling_out_edge_targets(
    graph: &CoverageGraph,
    from_bcb: BasicCoverageBlock,
    to_bcb: BasicCoverageBlock,
) -> impl Iterator<Item = BasicCoverageBlock> + Captures<'_>

Yields the graph successors of from_bcb that aren’t to_bcb. This is used when creating a counter expression for SiteCounter::EdgeDiffExpr.

For example, in this diagram the sibling out-edge targets of edge AC are the nodes B and D.
