Struct Sha1Embedder 

pub struct Sha1Embedder;

Hash-based fallback embedder (the original SHA1 implementation).

Deterministic, offline, and fast. Not semantically meaningful but keeps retrieval working without network or model configuration.

Implementations

impl Sha1Embedder

pub const fn new() -> Self

Trait Implementations

impl Default for Sha1Embedder

fn default() -> Self

Returns the “default value” for a type.

impl Embedder for Sha1Embedder

fn embed<'life0, 'life1, 'async_trait>( &'life0 self, text: &'life1 str, ) -> Pin<Box<dyn Future<Output = Result<Vec<f32>, CoreError>> + Send + 'async_trait>>

where Self: 'async_trait, 'life0: 'async_trait, 'life1: 'async_trait,

fn dim(&self) -> usize

fn is_semantic(&self) -> bool

Whether this embedder produces semantically meaningful vectors. Defaults to true so real embedding providers don’t have to opt in; lexical-only fallbacks override to false so hybrid retrieval knows to lean harder on the FTS baseline for keyword-heavy queries.
