Struct QueryResult 

pub struct QueryResult { /* private fields */ }

The complete result of a query: a collection of Arrow RecordBatches.

Use for row in result (yields Row) for row-oriented access, or QueryResult::record_batches() for direct Arrow access.

Implementations

impl QueryResult

pub fn new(schema: SchemaRef, batches: Vec<RecordBatch>) -> Self

pub fn schema(&self) -> &SchemaRef

pub fn record_batches(&self) -> &[RecordBatch]

The underlying Arrow record batches (zero-copy).

pub fn num_rows(&self) -> usize

Total number of rows across all batches.

pub fn column_names(&self) -> Vec<&str>

Column names in schema order.

pub fn rows(self) -> Result<Vec<Row>, Error>

Collect all rows into a Vec<Row>.

Trait Implementations

impl IntoIterator for QueryResult

type Item = Result<Row, Error>

The type of the elements being iterated over.

type IntoIter = QueryIterator

Which kind of iterator are we turning this into?

fn into_iter(self) -> Self::IntoIter

Creates an iterator from a value.
