Struct ShadowOutcome 

pub struct ShadowOutcome {
    pub primary: ResponseRecord,
    pub shadow: Option<ResponseRecord>,
    pub divergence: Option<Divergence>,
    pub skipped_by_sampler: bool,
    pub shadow_failed: Option<String>,
}

Result of a shadow call. The client always sees primary — even if the shadow leg failed or timed out, only telemetry is affected.

Fields

primary: ResponseRecord

The primary response. This is what the calling code should return.

shadow: Option<ResponseRecord>

The shadow response, if it succeeded inside the configured timeout.

divergence: Option<Divergence>

Structured diff. None when bodies/status/headers all match (modulo the config’s ignore list) or when the shadow didn’t run.

skipped_by_sampler: bool

True when the request would have been mirrored but the sampler said no.

shadow_failed: Option<String>

True when the shadow leg timed out / errored.
