Struct WrapperReceipt 

pub struct WrapperReceipt {
    pub outcome: WrapperOutcome,
    pub nodes: Vec<NodeCacheStatus>,
    pub total_wall_clock_ms: u64,
    pub docker_ran: bool,
    pub fell_through_reason: Option<String>,
}

The typed, serde-serializable “JSON receipt out” half of the keyway contract.

Fields

outcome: WrapperOutcome

nodes: Vec<NodeCacheStatus>

total_wall_clock_ms: u64

u64 milliseconds — see WrapperOutcome::CacheMiss for why not u128 (serde_json + internally-tagged-enum round-trip).

docker_ran: bool

fell_through_reason: Option<String>

Set when the cache accelerator could not be consulted and the wrapper degraded to a plain real docker build — e.g. the graph hasher rejected a Dockerfile that real docker builds fine (our scoped parser is deliberately narrower than BuildKit), or the cache backend itself errored (a transient Redis/Postgres hiccup). The cache is an optimization: any cache-side trouble degrades to a correct build, it never breaks one — this field makes that degrade observable rather than silent. None on the normal (cache consulted successfully) path.

Implementations

impl WrapperReceipt

pub fn to_json(&self) -> Result<String, Error>

Render this receipt as pretty JSON — the canonical keyway output surface (never format!() of ad-hoc fields).

Errors

Propagates any serde_json serialization failure (never expected for this fully-owned type, but kept fallible per the typed-emission contract).
