Enum IdentityResolution 

pub enum IdentityResolution {
    Resolved,
    Fallback,
    Unresolved,
    Unknown,
}

How a FunctionIdentity was produced by the upstream coverage pipeline.

Lets fallow-cloud aggregation and the CLI distinguish “this identity was resolved through a source map” from “this is a best-effort line-only fallback” without inspecting the column / span fields directly. Added in protocol 0.6.0.

Variants

Resolved

Identity was produced from a fully-resolved source location, e.g. a source-map lookup succeeded for a bundled position, or a direct AST traversal yielded byte-accurate columns.

Fallback

Identity was constructed via a best-effort fallback after a more precise resolution failed (missing source map, stale offsets, etc). FunctionIdentity::stable_id is bit-identical to what a IdentityResolution::Resolved producer would emit for the same function (the hash inputs are file / name / start_line only, none of which the fallback path loses); the confidence delta is about the column / span metadata, not the join key itself. Consumers that weight join confidence on this variant SHOULD apply the weight to display / disambiguation logic (column accuracy, source-map traceability), not to the join.

Unresolved

Identity could not be resolved beyond file, name, and start_line; columns and source_hash are SHOULD-be-absent. Consumers SHOULD ignore FunctionIdentity::start_column, FunctionIdentity::end_column, and FunctionIdentity::source_hash when resolution == Unresolved, even if a non-conforming producer populated them. The protocol intentionally documents rather than enforces this (a serde-time check would force every consumer to validate); unresolved_identity_with_columns_round_trips locks the document-but-tolerate stance.

Unknown

Sentinel for forward-compatibility with newer pipelines.

Trait Implementations

impl Clone for IdentityResolution

fn clone(&self) -> IdentityResolution

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for IdentityResolution

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for IdentityResolution

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl PartialEq for IdentityResolution

fn eq(&self, other: &IdentityResolution) -> 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.

impl Serialize for IdentityResolution

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.
