Struct ReplayAdapter 

pub struct ReplayAdapter { /* private fields */ }

Deterministic adapter that returns fixture-pinned responses.

Thread-safe: holds an in-memory map keyed by (model, prompt_hash).

Implementations

impl ReplayAdapter

pub fn new<P: Into<PathBuf>>(fixtures_dir: P) -> Result<Self, LlmError>

Construct a new replay adapter rooted at fixtures_dir.

The directory MUST contain an INDEX.toml listing every trusted fixture and its expected BLAKE3 hash. Any fixture in the directory that is not listed in the index, or whose on-disk bytes hash to a different value than the index records, causes LlmError::FixtureIntegrityFailed.

The check is upfront — once new() returns, the in-memory map is trusted for the lifetime of the adapter.

pub fn fixtures_dir(&self) -> &Path

Path the adapter is rooted at.

pub fn fixture_count(&self) -> usize

Number of trusted fixtures currently loaded.

Trait Implementations

impl Debug for ReplayAdapter

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

Formats the value using the given formatter.

impl LlmAdapter for ReplayAdapter

fn adapter_id(&self) -> &'static str

Stable, lowercase identifier used in audit envelopes (e.g. "claude", "ollama", "replay"). Constants — implementations MUST NOT vary this per call.

fn complete<'life0, 'async_trait>( &'life0 self, req: LlmRequest, ) -> Pin<Box<dyn Future<Output = Result<LlmResponse, LlmError>> + Send + 'async_trait>>

where Self: 'async_trait, 'life0: 'async_trait,

Issue a completion call. The adapter is responsible for honouring req.timeout_ms and returning LlmError::Timeout when exceeded.

fn stream( &self, req: LlmRequest, ) -> impl Stream<Item = Result<StreamChunk, LlmError>> + Send

where Self: Sized,

Stream tokens incrementally. Default implementation calls complete and yields the full response as a single chunk — adapters override this for true streaming.

fn stream_boxed(&self, req: LlmRequest) -> BoxStream<'_>

Object-safe streaming entry point. Returns a heap-allocated Pin<Box<dyn Stream>> so callers with only a &dyn LlmAdapter reference can drive streaming without knowing the concrete adapter type.
