Enum ScalarValue 

pub enum ScalarValue {
    Int64(i64),
    Float64(f64),
    Bool(bool),
    StringIndex(u32),
}

Scalar value for Ring 0 predicate comparison.

Fixed-size, stack-allocated, no heap. The StringIndex variant uses a pre-interned index into the StringInternTable, avoiding heap allocation during evaluation.

Variants

Int64(i64)

64-bit signed integer.

Float64(f64)

64-bit floating point.

Bool(bool)

Boolean.

StringIndex(u32)

Interned string index (not the string itself).

At filter compile time, string literals are interned into a StringInternTable. At evaluation time, the column’s string value is compared against the resolved string. Comparison is O(n) on string length but avoids allocation.

Trait Implementations

impl Clone for ScalarValue

fn clone(&self) -> ScalarValue

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ScalarValue

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

Formats the value using the given formatter.

impl PartialEq for ScalarValue

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