Module mapping 

luci-mapping — field types, mappings, and dynamic field detection.

This crate defines how fields are indexed: which fields exist, what types they have, and how unknown fields are handled. Mappings are instructions to the indexing pipeline, not structural constraints on documents.

See [[architecture-api-surface#Schema and Mappings]] for the full design.

Structs

FieldMapping

A single field’s mapping: its name, type, and indexing flags.

Mapping

An ordered set of field mappings with name-to-ID lookup.

MappingBuilder

Incrementally builds a Mapping.

Enums

DynamicMode

Controls how documents with unknown fields are handled.

FieldType

The data type of a field in a Luci index.

QuantizationType

Quantization scheme for dense_vector fields.

Functions

detect_field_type

Infer a FieldType from a JSON value using Elasticsearch’s dynamic mapping rules.
