Enum DbValue 

#[repr(C, u8)]
pub enum DbValue {
    Null,
    Integer(i64),
    Real(f64),
    Text(AzString),
    Blob(U8Vec),
}

A single SQL value — a bound statement parameter or a result cell. Mirrors SQLite’s storage classes (Null / Integer / Real / Text / Blob) but names nothing engine-specific.

Variants

Null

SQL NULL.

Integer(i64)

64-bit signed integer.

Real(f64)

64-bit IEEE float.

Text(AzString)

UTF-8 text.

Blob(U8Vec)

Raw bytes.

Implementations

impl DbValue

pub fn is_null(&self) -> bool

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

pub fn as_real(&self) -> Option<f64>

pub fn as_text(&self) -> Option<&AzString>

Trait Implementations

impl Clone for DbValue

fn clone(&self) -> DbValue

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for DbValue

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

Formats the value using the given formatter.

impl FromIterator<DbValue> for DbValueVec

fn from_iter<T>(iter: T) -> Self

where T: IntoIterator<Item = DbValue>,

Creates a value from an iterator.

impl PartialEq for DbValue

fn eq(&self, other: &DbValue) -> 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.
