Module constants 

Cross-cutting, shared constants.

Prefer deriving secondary constants (e.g. byte sizes) from primary ones to avoid drift.

Dimension Invariants

The embedding dimension values are treated as compile-time invariants across many modules (embedding, vectordb, cache, scoring). If you need runtime-configurable dimensions:

1. Use DimConfig to pass dimensions through initialization
2. Use validate_embedding_dim at module boundaries to catch mismatches early
3. The compile-time constants remain as defaults and for static size calculations

Structs

DimConfig

Runtime dimension configuration for modules that support dynamic embedding sizes.

Enums

DimValidationError

Error returned when dimension validation fails.

Constants

DEFAULT_EMBEDDING_DIM

Default embedding vector dimension.

DEFAULT_MAX_SEQ_LEN

Default maximum sequence length for models that support truncation.

DEFAULT_VECTOR_SIZE_U64

Default vector size exported as u64 for Qdrant APIs.

DEFAULT_VERIFICATION_THRESHOLD

Default L3 verification threshold.

EMBEDDING_BQ_BYTES

Default embedding size in bytes when stored as binary quantization (1 bit/dim).

EMBEDDING_F16_BYTES

Default embedding size in bytes when stored as f16.

EMBEDDING_F32_BYTES

Default embedding size in bytes when stored as f32.

Functions

validate_embedding_dim

Validates that a runtime embedding dimension matches the expected dimension.
