Struct StatementNode

pub struct StatementNode {
    pub lhs: Box<AssignableKind>,
    pub rhs: Box<ExprKind>,
}

Represents a statement node in the AST, such as variable = value.

Fields

lhs: Box<AssignableKind>

The left-hand side of the statement, usually a variable.

rhs: Box<ExprKind>

The right-hand side of the statement, the value to assign.

Implementations

impl StatementNode

pub fn new( lhs: Box<AssignableKind>, rhs: Box<ExprKind>, ) -> Result<Self, AstNodeError>

Creates a new StatementNode after validating lhs and rhs types.

Arguments

• lhs - The left-hand side of the statement.
• rhs - The right-hand side of the statement.

Returns

A new StatementNode.

Errors

Returns an AstNodeError if lhs or rhs is of an unsupported type.

Trait Implementations

impl AstVisitable for StatementNode

fn accept(&self, visitor: &mut dyn AstVisitor)

Accepts the visitor and calls the appropriate visit method.

fn clone_box(&self) -> Box<Self>

where Self: Sized,

Clones the AST node as a boxed trait object.

impl Clone for StatementNode

fn clone(&self) -> StatementNode

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for StatementNode

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for StatementNode

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl From<StatementNode> for AstKind

fn from(id: StatementNode) -> Self

Converts to this type from the input type.

impl From<StatementNode> for Box<AstKind>

fn from(id: StatementNode) -> Self

Converts to this type from the input type.

impl PartialEq for StatementNode

fn eq(&self, other: &Self) -> 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 Serialize for StatementNode

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.
