Struct CoverageRow 

pub struct CoverageRow {
    pub run_id: String,
    pub workspace: String,
    pub surface_key: String,
    pub kind: String,
    pub id: String,
    pub mode: String,
    pub verdict: String,
    pub reason: String,
    pub ts_micros: i64,
}

One persisted coverage row — the surface_coverage warehouse fact, mirroring tests/mcp_tool_coverage.json but for the WHOLE discovered surface. One row per (surface_key, mode, workspace) with its Verdict.

surface_key is SurfaceNode::key_str ("kind:id@mode") — the stable join key the gate matched coverage on. kind/id/mode are split out as columns so the warehouse / viz can filter without re-parsing the key.

Fields

run_id: String

The run that produced this row (groups one gate run’s rows).

workspace: String

The workspace this surface belongs to (so a multi-workspace warehouse keeps each workspace’s surface distinct).

surface_key: String

SurfaceNode::key_str() — "kind:id@mode". The stable identity.

kind: String

The enumerator kind tag (facett_component / viz_tab / cli_command / mcp_tool / function).

id: String

The surface id within its kind (component / tab / cmd / tool / fn path).

mode: String

The thin/fat mode (fat / thin / na).

verdict: String

covered / allowlisted / missing.

reason: String

The allowlist reason (only set when verdict == allowlisted).

ts_micros: i64

Row timestamp (micros). Shared across one run’s rows.

Implementations

impl CoverageRow

pub fn from_node( run_id: &str, workspace: &str, node: &SurfaceNode, verdict: Verdict, reason: &str, ts_micros: i64, ) -> Self

Build a row from a node + verdict (the writer’s per-node mapping).

pub fn verdict(&self) -> Verdict

The parsed verdict (defaults to Verdict::Missing for an unknown tag — fail-safe: an unrecognized verdict counts against the gate, never for it).

Trait Implementations

impl Clone for CoverageRow

fn clone(&self) -> CoverageRow

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for CoverageRow

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for CoverageRow

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Eq for CoverageRow

impl PartialEq for CoverageRow

fn eq(&self, other: &CoverageRow) -> 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 CoverageRow

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

where __S: Serializer,

Serialize this value into the given Serde serializer.
