pub struct TextColdDir { /* private fields */ }

Implementations

impl TextColdDir

pub fn cold_stats(&self, tokens: &[Vec<u8>]) -> (u64, u64, Vec<(Vec<u8>, u32)>)

Pass-1 contribution: summed LIVE docs/length plus per-token live df across every cold segment (one fence descent per token per segment; the doc/length halves are in-memory numbers, no I/O at all).

pub fn cold_page(&self, q: &ColdPageQuery<'_>) -> ColdPage

Pass-2 contribution: the clause-faithful cold page (see the module doc for what each clause does here).

impl TextColdDir

pub fn new() -> Self

pub fn has_cold(&self) -> bool

pub fn on_row_write(&mut self, row_key: &[u8])

The write path saw this row change: shadow its frozen entries and withdraw its statistics, exactly, in every segment that holds it (its forward record says which, and what to subtract).

pub fn freeze_batch( &mut self, ts: &mut TextSegment, index_name: &[u8], keys: &[Vec<u8>], segs_dir: &Path, ) -> Result<bool, String>

Freeze keys out of the hot text segment into one sealed bucket segment. Failure leaves the hot segment SHRUNK but the batch unfrozen on disk — acceptable for derived spill (the entries are rebuildable from rows), reported to the caller.

Trait Implementations

impl Default for TextColdDir

fn default() -> Self

Returns the “default value” for a type.
