Enum rustc_session::config::CoverageLevel
source · pub enum CoverageLevel {
Block,
Branch,
Condition,
Mcdc,
}
Expand description
Controls whether branch coverage or MC/DC coverage is enabled.
Variants§
Block
Instrument for coverage at the MIR block level.
Branch
Also instrument branch points (includes block coverage).
Condition
Same as branch coverage, but also adds branch instrumentation for certain boolean expressions that are not directly used for branching.
For example, in the following code, b
does not directly participate
in a branch, but condition coverage will instrument it as its own
artificial branch:
let x = a && b;
// ^ last operand
This level is mainly intended to be a stepping-stone towards full MC/DC instrumentation, so it might be removed in the future when MC/DC is sufficiently complete, or if it is making MC/DC changes difficult.
Mcdc
Instrument for MC/DC. Mostly a superset of condition coverage, but might differ in some corner cases.

attributes. Please see the Rust Reference's “Type Layout” chapter for details on type layout guarantees.
