Enum Variable 

pub enum Variable {
    Identifier(Identifier),
    Field(Box<FieldExpression>),
    Index(Box<IndexExpression>),
}

Represents a variable reference.

Variants

Identifier(Identifier)

A simple named variable (e.g., x, count, self).

Field(Box<FieldExpression>)

A field access on a table or object using dot notation (e.g., table.field, self.name).

Index(Box<IndexExpression>)

An index access on a table using bracket notation (e.g., array[1], table[key]).

Implementations

impl Variable

pub fn new<S: Into<String>>(name: S) -> Self

Creates a new variable from an identifier name.

pub fn mutate_first_token(&mut self) -> &mut Token

Returns a mutable reference to the first token for this variable, creating it if missing.

pub fn mutate_last_token(&mut self) -> &mut Token

Returns a mutable reference to the last token for this variable, creating it if missing.

Trait Implementations

impl Clone for Variable

fn clone(&self) -> Variable

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Variable

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

Formats the value using the given formatter.

impl From<FieldExpression> for Variable

fn from(field: FieldExpression) -> Self

Converts to this type from the input type.

impl From<Identifier> for Variable

fn from(identifier: Identifier) -> Self

Converts to this type from the input type.

impl From<IndexExpression> for Variable

fn from(index: IndexExpression) -> Self

Converts to this type from the input type.

impl From<Variable> for Expression

fn from(variable: Variable) -> Self

Converts to this type from the input type.

impl PartialEq for Variable

fn eq(&self, other: &Variable) -> 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 Eq for Variable

impl StructuralPartialEq for Variable
