Struct QueryRowsBuilder 

pub struct QueryRowsBuilder { /* private fields */ }

Builds immutable query results without retaining one map or vector per row.

The first named row binds column names to stable ordinals. Later rows are consumed in the same deterministic BTreeMap order and their values move directly into one flat buffer.

Implementations

impl QueryRowsBuilder

pub fn new() -> Self

pub fn with_row_capacity(row_capacity: usize) -> Self

pub fn with_schema(schema: QuerySchema, row_capacity: usize) -> Self

pub fn push_values( &mut self, values: impl IntoIterator<Item = Value>, ) -> Result<()>

pub fn try_push_values( &mut self, values: impl IntoIterator<Item = Result<Value>>, ) -> Result<()>

Appends one fallible row directly into the flat value buffer.

A conversion error or width mismatch rolls the partial row back.

pub fn push_named_row(&mut self, row: Row) -> Result<()>

pub fn finish(self) -> QueryRows
