Struct QueryResult 

pub struct QueryResult { /* private fields */ }

Collected result of a query: all rows’ column offsets plus metadata.

Data lives in an Arena; this struct holds only the offset/length bookkeeping. Access rows via row() or rows().

Example

for row in result.rows(&arena) {
    // Access columns by index
}

Implementations

impl QueryResult

pub fn from_parts( all_col_offsets: Vec<(usize, i32)>, num_cols: usize, columns: Arc<[ColumnDesc]>, affected_rows: u64, ) -> QueryResult

Construct a QueryResult from its constituent parts.

Used by bsql-core’s streaming layer to assemble per-chunk results.

pub fn from_parts_with_buf( all_col_offsets: Vec<(usize, i32)>, num_cols: usize, columns: Arc<[ColumnDesc]>, affected_rows: u64, data_buf: Vec<u8>, ) -> QueryResult

Construct with inline data buffer (zero-copy from wire).

pub fn len(&self) -> usize

Number of rows in the result.

pub fn is_empty(&self) -> bool

Whether the result set is empty.

pub fn affected_rows(&self) -> u64

Number of affected rows (for INSERT/UPDATE/DELETE).

pub fn columns(&self) -> &[ColumnDesc]

Column descriptors.

pub fn row<'a>(&'a self, idx: usize, arena: &'a Arena) -> Row<'a>

Get a row by index. The returned Row borrows from the arena or the inline data buffer.

pub fn take_col_offsets(&mut self) -> Vec<(usize, i32)>

Take the col_offsets vec out of this result, leaving it empty.

Used by QueryStream to reclaim and reuse the allocation between chunks instead of allocating a new Vec per chunk.

pub fn take_data_buf(&mut self) -> Option<Vec<u8>>

Take the data buffer for recycling. Returns None if no data_buf.

pub fn rows<'a>(&'a self, arena: &'a Arena) -> impl Iterator<Item = Row<'a>>

Iterate over rows.
