Struct QueryResult 

pub struct QueryResult {
    pub columns: Vec<String>,
    pub rows: Vec<Vec<Value>>,
    pub rows_affected: u64,
}

Result of a SQL query or multi-modal query.

Fields

columns: Vec<String>

Column names.

rows: Vec<Vec<Value>>

Rows of values. Each row has one value per column.

rows_affected: u64

Number of rows affected (for INSERT/UPDATE/DELETE).

Implementations

impl QueryResult

pub fn empty() -> Self

Empty result set with no columns.

pub fn row_count(&self) -> usize

Number of rows in the result set.

pub fn row_as_map(&self, index: usize) -> Option<HashMap<&str, &Value>>

Get a single row as a HashMap<column_name, value>.

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<'de> Deserialize<'de> for QueryResult

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

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.

impl Serialize for QueryResult

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.
