Struct Rows 

pub struct Rows<'a> { /* private fields */ }

Stepping iterator over query rows. Obtained from PreparedStatement::query.

Uses a lending-iterator pattern: next() returns Result<Option<Row<'_>>> where the Row borrows from &mut self. Incompatible with std::iter::Iterator because the row’s lifetime is tied to the stepper — same design as rusqlite’s Rows.

Implementations

impl<'a> Rows<'a>

pub fn next(&mut self) -> Result<Option<Row<'_>>>

Step to the next row, if any.

pub fn column_count(&self) -> usize

Number of output columns.

pub fn column_names(&self) -> &[String]

Output column names.

pub fn collect(self) -> Result<QueryResult>

Drain all remaining rows into a QueryResult.
