Struct FtsPostingCell 

pub struct FtsPostingCell {
    pub cell_id: i64,
    pub term: String,
    pub entries: Vec<(i64, u32)>,
}

One FTS posting list cell — either a per-term postings entry or the single doc-lengths sidecar (when term.is_empty()).

Fields

cell_id: i64

Sequential id assigned at save time. Acts as the B-Tree slot directory key; never persisted as part of the index logic.

term: String

Lowercased ASCII term. Empty on the doc-lengths sidecar.

entries: Vec<(i64, u32)>

(rowid, value) pairs. value is term frequency for posting cells, doc length for the sidecar.

Implementations

impl FtsPostingCell

pub fn posting(cell_id: i64, term: String, entries: Vec<(i64, u32)>) -> Self

pub fn doc_lengths(cell_id: i64, entries: Vec<(i64, u32)>) -> Self

Constructs the doc-lengths sidecar cell (term left empty).

pub fn encode(&self) -> Result<Vec<u8>>

Encodes the cell into a freshly-allocated Vec<u8>. The result starts with the shared cell_length | kind_tag prefix and is directly usable as a slot-directory entry on a TableLeaf-style page.

pub fn decode(buf: &[u8], pos: usize) -> Result<(FtsPostingCell, usize)>

Decodes one cell starting at pos. Returns the cell plus the total bytes consumed (including the leading length varint).

pub fn is_doc_lengths(&self) -> bool

True iff this cell is the doc-lengths sidecar.

Trait Implementations

impl Clone for FtsPostingCell

fn clone(&self) -> FtsPostingCell

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for FtsPostingCell

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl PartialEq for FtsPostingCell

fn eq(&self, other: &FtsPostingCell) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
