Trait Query

pub trait Query<F, T>
where
    F: FnMut(&mut ResultRow<'_, '_>) -> SqliteResult<T>,
{
    // Required method
    fn query<'stmt>(
        &'stmt mut self,
        values: &[&dyn ToSql],
        txform: F,
    ) -> SqliteResult<QueryResults<'stmt, T, F>>;
}

Mix in query() convenience function.

Required Methods

fn query<'stmt>( &'stmt mut self, values: &[&dyn ToSql], txform: F, ) -> SqliteResult<QueryResults<'stmt, T, F>>

Iterate over query results after binding parameters.

Each of the values is bound to the statement (using to_sql) and the statement is executed.

Returns an iterator over rows transformed by txform, which computes a value for each row (or an error).
