Struct ResultSet 

pub struct ResultSet { /* private fields */ }

A single result set within a multi-result batch.

Rows are stored as PendingRow values that may be either already-decoded Rows (eager path, used by tests and direct construction) or raw TDS bytes (lazy path, used by crate::Client::call_procedure and crate::Client::query_multiple). Decoding happens on pull, so per-row decode errors surface through ResultSet::next_row and ResultSet::collect_all.

Implementations

impl ResultSet

pub fn new(columns: Vec<Column>, rows: Vec<Row>) -> Self

Create a new result set from already-decoded rows.

This is the eager constructor used by tests and callers that already hold typed Rows. Production query paths use ResultSet::from_raw (private) to defer row decoding.

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

Get the column metadata.

pub fn rows_remaining(&self) -> usize

Get the number of rows remaining.

pub fn next_row(&mut self) -> Option<Result<Row, Error>>

Get the next row from this result set.

Returns None when no more rows remain, or Some(Err(_)) when the next pending row fails to decode. The stream is not short-circuited on decode error — the caller may continue to pull subsequent rows.

pub fn is_empty(&self) -> bool

Check if this result set is empty.

pub fn collect_all(&mut self) -> Result<Vec<Row>, Error>

Collect all remaining rows into a vector.

Stops at the first decode error and returns it.
