Struct FastFieldWriter 

pub struct FastFieldWriter {
    pub column_type: FastFieldColumnType,
    /* private fields */
}

Collects values during indexing and serializes a single fast-field column.

Fields

column_type: FastFieldColumnType

Implementations

impl FastFieldWriter

pub fn new_numeric(column_type: FastFieldColumnType) -> Self

Create a writer for a numeric column (u64/i64/f64).

pub fn new_text() -> Self

Create a writer for a text ordinal column.

pub fn add_u64(&mut self, doc_id: u32, value: u64)

Record a numeric value for doc_id. Fills gaps with 0.

pub fn add_i64(&mut self, doc_id: u32, value: i64)

Record an i64 value (zigzag-encoded).

pub fn add_f64(&mut self, doc_id: u32, value: f64)

Record an f64 value (sortable-encoded).

pub fn add_text(&mut self, doc_id: u32, value: &str)

Record a text value (dictionary-encoded at build time).

pub fn pad_to(&mut self, num_docs: u32)

Ensure the values array covers num_docs entries.

pub fn num_docs(&self) -> u32

Number of documents in this column.

pub fn serialize( &mut self, writer: &mut dyn Write, data_offset: u64, ) -> Result<(FastFieldTocEntry, u64)>

Serialize column data to writer. Returns (data_offset_start, data_size).

For text columns, also writes dictionary after the column data. Returns (toc_entry_without_offsets, dict_bytes_written).
