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

Implementations

impl BcbBranch

pub fn from_to(
    from_bcb: BasicCoverageBlock,
    to_bcb: BasicCoverageBlock,
    basic_coverage_blocks: &CoverageGraph
) -> Self

pub fn counter<'a>(
    &self,
    basic_coverage_blocks: &'a CoverageGraph
) -> Option<&'a CoverageKind>

pub fn is_only_path_to_target(&self) -> bool

Trait Implementations

impl Clone for BcbBranch

fn clone(&self) -> BcbBranch

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for BcbBranch

fn fmt(&self, fmt: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl PartialEq<BcbBranch> for BcbBranch

fn eq(&self, other: &BcbBranch) -> bool

This method tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

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.
