Struct MockSparseEncoder 

pub struct MockSparseEncoder { /* private fields */ }

Deterministic test-only encoder. Produces a SparseEmbed by hashing each whitespace-separated token into the first 1024 vocabulary slots with a length-inverse weight (1.0 / (1.0 + token_len)).

Not a real SPLADE; do not use in benchmarks. Its purpose is to let Retriever::with_sparse_ranker(...) unit-test the fusion lane without pulling ONNX Runtime into mnem-core’s test deps.

Trait Implementations

impl Clone for MockSparseEncoder

fn clone(&self) -> MockSparseEncoder

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for MockSparseEncoder

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

Formats the value using the given formatter.

impl Default for MockSparseEncoder

fn default() -> Self

Returns the “default value” for a type.

impl SparseEncoder for MockSparseEncoder

fn model(&self) -> &str

Provider + model identifier. Lowercase, colon-separated by convention (e.g. "splade:opensearch-doc-v3-distill", "bgem3:sparse", "mock:len-inverse").

fn vocab_id(&self) -> &str

Vocabulary identifier. Passed through to SparseEmbed::vocab_id on every emitted embedding.

fn encode(&self, text: &str) -> Result<SparseEmbed, SparseError>

Encode a document-side text string into a sparse vector. This is the path run at ingest time.

fn encode_query(&self, text: &str) -> Result<SparseEmbed, SparseError>

Encode a query-side text string into a sparse vector.
