Struct HashSearchIterator 

pub struct HashSearchIterator { /* private fields */ }

Iterator for RediSearch FT.SEARCH results.

Unlike HashBatchIterator which uses SCAN, this iterator uses RediSearch’s FT.SEARCH with LIMIT for pagination, enabling server-side filtering.

Implementations

impl HashSearchIterator

pub fn new( url: &str, schema: HashSchema, config: SearchBatchConfig, projection: Option<Vec<String>>, ) -> Result<Self>

Create a new HashSearchIterator.

Arguments

• url - Redis connection URL
• schema - Schema defining the expected fields and types
• config - Search configuration (index, query, etc.)
• projection - Optional list of fields to return

pub fn next_batch(&mut self) -> Result<Option<RecordBatch>>

Get the next batch of search results as a RecordBatch.

Returns None when iteration is complete.

pub fn is_done(&self) -> bool

pub fn rows_yielded(&self) -> usize

Get the number of rows yielded so far.

pub fn total_results(&self) -> Option<usize>

Get the total number of matching documents (available after first batch).
