Enum Operand 

pub enum Operand {
    Field(String),
    Number(String),
    StringLit(String),
    Bool(bool),
    EnumVariant(String),
}

An operand (leaf value) in a boolean expression.

Variants

Field(String)

A field reference (e.g. age, status).

Number(String)

A numeric literal (e.g. 18, 3.14).

StringLit(String)

A string literal (e.g. "hello").

Bool(bool)

A boolean literal (true / false).

EnumVariant(String)

A bare identifier inside an IN [...] list — treated as an enum variant.

Trait Implementations

impl Clone for Operand

fn clone(&self) -> Operand

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Operand

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

Formats the value using the given formatter.

impl Display for Operand

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

Formats the value using the given formatter.

impl PartialEq for Operand

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