Enum CompactValue 

#[repr(u8)]
pub enum CompactValue {
    Null = 0,
    True = 1,
    False = 2,
    SmallInt(i8),
    Int(i64),
    Float(f64),
    String(String),
}

A compact filter value optimized for common cases.

Uses a tagged union representation to minimize size:

• Discriminant is inline with data
• Small strings can be stored inline (future optimization)

Variants

Null = 0

Null value.

True = 1

Boolean true.

False = 2

Boolean false.

SmallInt(i8)

Small integer (-128 to 127).

Int(i64)

Full integer.

Float(f64)

Float value.

String(String)

String value.

Implementations

impl CompactValue

pub fn into_filter_value(self) -> FilterValue

Convert to a FilterValue.

Trait Implementations

impl Clone for CompactValue

fn clone(&self) -> CompactValue

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for CompactValue

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

Formats the value using the given formatter.

impl From<&str> for CompactValue

fn from(v: &str) -> Self

Converts to this type from the input type.

impl From<CompactValue> for FilterValue

fn from(v: CompactValue) -> Self

Converts to this type from the input type.

impl From<String> for CompactValue

fn from(v: String) -> Self

Converts to this type from the input type.

impl From<bool> for CompactValue

fn from(v: bool) -> Self

Converts to this type from the input type.

impl From<f64> for CompactValue

fn from(v: f64) -> Self

Converts to this type from the input type.

impl From<i32> for CompactValue

fn from(v: i32) -> Self

Converts to this type from the input type.

impl From<i64> for CompactValue

fn from(v: i64) -> Self

Converts to this type from the input type.

impl PartialEq for CompactValue

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