Struct ReplaySummaryBackend 

pub struct ReplaySummaryBackend { /* private fields */ }

Deterministic fixture-backed summary backend for CI and tests.

Constructed from a HashMap<RequestKey, SummaryResponse> keyed by the canonical BLAKE3 of the request fields (SummaryRequest::request_hash). A lookup miss returns SummaryError::BackendNotConfigured with a detailed reason so test failure messages stay actionable.

Use ReplaySummaryBackend::from_fixture_file to load a JSON fixture keyed by (model_name, prompt_template_blake3, ordered source claims, max_output_bytes, decay_job_id).

Implementations

impl ReplaySummaryBackend

pub fn from_entries( entries: Vec<ReplaySummaryFixtureEntry>, ) -> Result<Self, SummaryError>

Construct a new replay backend from an in-memory request map.

Duplicate request hashes are refused: the caller has either supplied two distinct fixtures that compute to the same request hash (cryptographic collision — implausible) or repeated the same fixture row by mistake (the more common case).

pub fn from_fixture_file(path: &Path) -> Result<Self, SummaryError>

Load a fixture file from disk and construct the backend.

File is a JSON document matching the ReplaySummaryFixture shape. Errors map to SummaryError::CallFailed with a descriptive message so CI logs are actionable.

pub fn fixture_count(&self) -> usize

Number of fixture entries currently held.

Trait Implementations

impl Clone for ReplaySummaryBackend

fn clone(&self) -> ReplaySummaryBackend

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ReplaySummaryBackend

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

Formats the value using the given formatter.

impl SummaryBackend for ReplaySummaryBackend

fn summarize( &self, request: &SummaryRequest, ) -> Result<SummaryResponse, SummaryError>

Issue a summary call. The implementation owns its own timeout budget and MUST surface timeouts as SummaryError::CallFailed.
