Struct rustc_mir::transform::coverage::graph::BcbBranch

pub(super) struct BcbBranch {
    pub edge_from_bcb: Option<BasicCoverageBlock>,
    pub target_bcb: BasicCoverageBlock,
}

Represents a successor from a branching BasicCoverageBlock (such as the arms of a SwitchInt) as either the successor BCB itself, if it has only one incoming edge, or the successor plus the specific branching BCB, representing the edge between the two. The latter case distinguishes this incoming edge from other incoming edges to the same target_bcb.

Fields

edge_from_bcb: Option<BasicCoverageBlock>

target_bcb: BasicCoverageBlock

Layout

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