Enum rustc_codegen_llvm::coverageinfo::ffi::RegionKind

#[repr(C)]
pub enum RegionKind {
    CodeRegion,
    ExpansionRegion,
    SkippedRegion,
    GapRegion,
    BranchRegion,
}

Corresponds to enum llvm::coverage::CounterMappingRegion::RegionKind.

Must match the layout of LLVMRustCounterMappingRegionKind.

Variants

CodeRegion

A CodeRegion associates some code with a counter

ExpansionRegion

An ExpansionRegion represents a file expansion region that associates a source range with the expansion of a virtual source file, such as for a macro instantiation or #include file.

SkippedRegion

A SkippedRegion represents a source range with code that was skipped by a preprocessor or similar means.

GapRegion

A GapRegion is like a CodeRegion, but its count is only set as the line execution count when its the only region in the line.

BranchRegion

A BranchRegion represents leaf-level boolean expressions and is associated with two counters, each representing the number of times the expression evaluates to true or false.

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.
