Enum MutantStatus 

pub enum MutantStatus {
    Survived,
    Killed,
    NoCoverage,
    Timeout,
    CompileError,
    RuntimeError,
}

A mutant’s outcome, normalized across the engines (Stryker / cosmic-ray / cargo-mutants) — the union of their result vocabularies reduced to what the gate needs (#239). Each language adapter maps its native outcomes onto this so the Rust core gates on one representation instead of three per-engine report formats. The serialized form is snake_case (no_coverage, compile_error, …) — the wire contract adapters emit.

Variants

Survived

A test ran the mutated code but none failed — a survivor.

Killed

A test failed on the mutant — caught.

NoCoverage

No test exercised the mutant at all — a survivor (worse than Survived).

Timeout

The mutant ran but the suite timed out — inconclusive, not a survivor (but viable).

CompileError

The mutant never compiled — not a viable mutant.

RuntimeError

The mutant errored at runtime before a test could judge it — not viable.

Trait Implementations

impl Clone for MutantStatus

fn clone(&self) -> MutantStatus

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for MutantStatus

impl Debug for MutantStatus

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for MutantStatus

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Eq for MutantStatus

impl PartialEq for MutantStatus

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

Tests for self and other values to be equal, and is used by ==.

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

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