Enum Value 

pub enum Value {
    Integer(i64),
    Text(String),
    Real(f64),
    Bool(bool),
    Null,
}

Runtime value produced by query execution. Separate from the on-disk Row enum so the executor can carry typed values (including NULL) across operators.

Variants

Integer(i64)

Text(String)

Real(f64)

Bool(bool)

Null

Implementations

impl Value

pub fn to_display_string(&self) -> String

Trait Implementations

impl Clone for Value

fn clone(&self) -> Value

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Value

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

Formats the value using the given formatter.

impl FromValue for Value

Identity impl so row.get::<_, Value>(0) works when you want untyped access.

fn from_value(v: &Value) -> Result<Self>

impl PartialEq for Value

fn eq(&self, other: &Value) -> 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 StructuralPartialEq for Value
