Struct RecordPool 

pub struct RecordPool {
    pub ids: Vec<u64>,
    pub columns: Vec<Vec<String>>,
    pub n_fields: usize,
}

Column-major record store: columns[field_idx][record_idx].

All field values are stored as UTF-8 strings in schema field order. Missing or non-text values become empty strings (treated as ComparisonLevel::None by every comparator).

The RecordId for record r is ids[r].

Fields

ids: Vec<u64>

columns: Vec<Vec<String>>

columns[field_idx][record_idx] = UTF-8 text value.

n_fields: usize

Implementations

impl RecordPool

pub fn new(n_fields: usize) -> RecordPool

pub fn from_records(records: &[Record], schema: &Schema) -> RecordPool

pub fn from_store( store: &dyn RecordStore, ids: &[u64], schema: &Schema, ) -> RecordPool

Build a pool from a RecordStore, loading only the records with IDs listed in ids. Records are inserted in ids order; pool position i corresponds to ids[i].

pub fn from_pairs(pairs: &[(Record, Record)], schema: &Schema) -> RecordPool

Build a pool from (Record, Record) pairs: record 2*i is side A of pair i, record 2*i+1 is side B. Allows compare_batch(&pairs) to build a pool once and delegate to compare_batch_from_pool.

pub fn with_capacity(cap: usize, n_fields: usize) -> RecordPool

pub fn push(&mut self, record: &Record, schema: &Schema)

Append one record. Fields are stored in schema order.

pub fn get(&self, field_idx: usize, record_idx: usize) -> &str

Direct column access: bytes of field f for record r.

pub fn len(&self) -> usize

pub fn is_empty(&self) -> bool

Trait Implementations

impl Clone for RecordPool

fn clone(&self) -> RecordPool

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for RecordPool

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

Formats the value using the given formatter.
