Hook for automatic vector embedding generation.

Implementations must be sync for safety across the WIT boundary.

Required Methods

fn vectorize_fields( &self, record: Value, mappings: &[FieldMapping], ) -> Result<Value, String>

Embed text/image fields in a record based on mappings.

fn vectorize_text(&self, text: &str, model: &str) -> Result<Vec<f32>, String>

Convert a text query to a vector for search.

fn vectorize_image(&self, bytes: &[u8], model: &str) -> Result<Vec<f32>, String>

Convert raw image bytes to a vector.

Provided Methods

fn validate_model(&self, _model: &str) -> Result<(), String>

Check if a model is available for use.

fn warmup_model(&self, _model: &str, _field_type: &str) -> Result<(), String>

Eagerly load a model into memory during startup.

fn vectorize_fields_batch( &self, records: Vec<Value>, mappings: &[FieldMapping], ) -> Result<Vec<Value>, String>

Batch-embed multiple records.

Dyn Compatibility

This trait is dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety".
