pub struct LookupResult { /* private fields */ }Expand description
The result of a lookup operation.
Contains the rows returned from a lookup. For primary key lookups, this will contain at most one row. For prefix key lookups (future), this may contain multiple rows.
Implementations§
Source§impl LookupResult
impl LookupResult
Sourcepub fn get_single_row(&self) -> Result<Option<CompactedRow<'_>>>
pub fn get_single_row(&self) -> Result<Option<CompactedRow<'_>>>
Returns the only row in the result set as a CompactedRow.
This method provides a zero-copy view of the row data, which means the returned
CompactedRow borrows from this result set and cannot outlive it.
§Returns
Ok(Some(row)): If exactly one row exists.Ok(None): If the result set is empty.Err(Error::UnexpectedError): If the result set contains more than one row.Err(Error): If the row payload is too short to contain a schema id.
Sourcepub fn get_rows(&self) -> Result<Vec<CompactedRow<'_>>>
pub fn get_rows(&self) -> Result<Vec<CompactedRow<'_>>>
Returns all rows in the result set as CompactedRows.
§Returns
Ok(rows)- All rows in the result set.Err(Error)- If any row payload is too short to contain a schema id.
Sourcepub fn to_record_batch(&self) -> Result<RecordBatch>
pub fn to_record_batch(&self) -> Result<RecordBatch>
Converts all rows in this result into an Arrow RecordBatch.
This is useful for integration with DataFusion or other Arrow-based tools.
§Returns
Ok(RecordBatch)- All rows in columnar Arrow format. Returns an empty batch (with the correct schema) if the result set is empty.Err(Error)- If the conversion fails.
