Enum QueryResult 

pub enum QueryResult {
    ResultSet {
        handle: Option<ResultSetHandle>,
        data: ResultData,
    },

        count: i64,
    },
}

Result of a query execution.

Variants

Fields

handle: Option<ResultSetHandle>

Handle for fetching more data (None if all data is in the response)

Implementations

impl QueryResult

pub fn result_set(handle: Option<ResultSetHandle>, data: ResultData) -> Self

Create a result set query result.

pub fn row_count(count: i64) -> Self

Create a row count query result.

pub fn is_result_set(&self) -> bool

Check if this is a result set.

pub fn is_row_count(&self) -> bool

Check if this is a row count.

pub fn handle(&self) -> Option<ResultSetHandle>

Get the result set handle if this is a result set. Returns None if all data was included in the initial response.

pub fn get_row_count(&self) -> Option<i64>

Get the row count if this is a row count result.

pub fn has_more_data(&self) -> bool

Check if this result has more data to fetch.

For column-major data, the number of rows is determined by the length of the first column (or 0 if no columns).
