Configuration for segment builder

Fields

temp_dir: PathBuf

Directory for temporary spill files

compression_level: CompressionLevel

Compression level for document store

num_compression_threads: usize

Width of the document-store compression pool. Concurrent builders with the same width share one process-wide executor.

interner_capacity: usize

Initial capacity for term interner

posting_map_capacity: usize

Initial capacity for posting lists hashmap

optimization: IndexOptimization

Term-dictionary compression / bloom configuration (from the index optimization mode).

posting_codec: PostingCodec

Posting block codec (docs/posting-codecs.md).

quantized_norms: bool

New plain-text columns use versioned byte4 norms. Existing segments retain their scores.

compact_text: bool

New position streams use a compact directory separate from payload pages.

posting_ratio_bounds: bool

Opt in to compact, score-independent length/TF block bounds.

posting_impact_bounds: bool

Opt in to bounded competitive frequency/length envelopes. Implies ratio bounds.

term_dict_block_size: SSTableBlockSize

Validated flush target for this segment’s term dictionary.

Implementations

impl SegmentBuilderConfig

pub fn effective_posting_bounds(&self) -> PostingBounds

Block-bound metadata this builder writes; impact bounds imply ratio bounds.

Trait Implementations

impl Clone for SegmentBuilderConfig

fn clone(&self) -> Self

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Default for SegmentBuilderConfig

fn default() -> Self

Returns the “default value” for a type.
