Struct QueryResult 

pub struct QueryResult {
    pub columns: Vec<ColumnInfo>,
    pub rows: Vec<Vec<SqlValue>>,
}

Result of a SELECT query.

Fields

columns: Vec<ColumnInfo>

Column information for the result set.

rows: Vec<Vec<SqlValue>>

Result rows as vectors of SqlValue.

Implementations

impl QueryResult

pub fn new(columns: Vec<ColumnInfo>, rows: Vec<Vec<SqlValue>>) -> Self

Create a new query result with column info and rows.

pub fn empty(columns: Vec<ColumnInfo>) -> Self

Create an empty query result with column info.

pub fn row_count(&self) -> usize

Returns the number of rows in the result.

pub fn column_count(&self) -> usize

Returns the number of columns in the result.

pub fn is_empty(&self) -> bool

Returns true if the result is empty.

Trait Implementations

impl Clone for QueryResult

fn clone(&self) -> QueryResult

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for QueryResult

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl PartialEq for QueryResult

fn eq(&self, other: &QueryResult) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
