Struct tantivy::fieldnorm::FieldNormReaders

pub struct FieldNormReaders { /* private fields */ }

Reader for the fieldnorm (for each document, the number of tokens indexed in the field) of all indexed fields in the index.

Each fieldnorm is approximately compressed over one byte. We refer to this byte as fieldnorm_id. The mapping from fieldnorm to fieldnorm_id is given by monotonic.
