Enum ExprKind

pub enum ExprKind {
    Constant,
    Variable,
    Function {
        arity: usize,
    },
    Array,
    Attribute,
}

Classifies the kind of expression node in the AST.

This enum is used to categorize expression nodes at a higher level than the specific AST node variants, making it easier to determine the general type of an expression without matching on all variants.

Variants

Constant

A constant numerical value.

Variable

A variable reference.

Function

A function call with a specific arity (number of arguments).

Fields

arity: usize

Number of arguments the function takes

Array

An array element access.

Attribute

An object attribute access.

Trait Implementations

impl Clone for ExprKind

fn clone(&self) -> ExprKind

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ExprKind

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

Formats the value using the given formatter.

impl PartialEq for ExprKind

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