Enum CoverageKind 

pub enum CoverageKind {
    Point {
        point_kind: PointKind,
        hir_id: HirId,
    },
    BlockMarker {
        id: BlockMarkerId,
    },
    VirtualCounter {
        bcb: BasicCoverageBlock,
    },
}

Variants

Point

Associates a HIR node (such as an expression) with a particular point in MIR control-flow. The relationship between the node and the point is indicated by PointKind. Injected during MIR building.

Fields

point_kind: PointKind

hir_id: HirId

BlockMarker

Marks its enclosing basic block with an ID that can be referred to by side data in CoverageEarlyInfo.

Should be erased before codegen (at some point after InstrumentCoverage).

Fields

id: BlockMarkerId

VirtualCounter

Marks its enclosing basic block with the ID of the coverage graph node that it was part of during the InstrumentCoverage MIR pass.

During codegen, this might be lowered to llvm.instrprof.increment or to a no-op, depending on the outcome of counter-creation.

Fields

bcb: BasicCoverageBlock

Implementations

impl CoverageKind

pub fn is_removed_after_analysis(&self) -> bool

Returns true if this kind of coverage statement is a marker inserted during MIR building, for use by analysis in the InstrumentCoverage pass, and is no longer needed after that pass.

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.
