Enum rhai::ASTNode

#[non_exhaustive]
pub enum ASTNode<'a> {
    Stmt(&'a Stmt),
    Expr(&'a Expr),
}

(internals) An AST node, consisting of either an Expr or a Stmt. Exported under the internals feature only.

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

Stmt(&'a Stmt)

A statement (Stmt).

Expr(&'a Expr)

An expression (Expr).

Implementations

impl ASTNode<'_>

pub const fn is_stmt(&self) -> bool

Is this ASTNode a Stmt?

pub const fn is_expr(&self) -> bool

Is this ASTNode an Expr?

pub fn position(&self) -> Position

Get the Position of this ASTNode.

Trait Implementations

impl<'a> Clone for ASTNode<'a>

fn clone(&self) -> ASTNode<'a>

Returns a copy of the value.

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

Performs copy-assignment from source.

impl<'a> Debug for ASTNode<'a>

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

Formats the value using the given formatter.

impl<'a> From<&'a Expr> for ASTNode<'a>

fn from(expr: &'a Expr) -> Self

Converts to this type from the input type.

impl<'a> From<&'a Stmt> for ASTNode<'a>

fn from(stmt: &'a Stmt) -> Self

Converts to this type from the input type.

impl<'a> Hash for ASTNode<'a>

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl PartialEq<ASTNode<'_>> for ASTNode<'_>

fn eq(&self, other: &Self) -> bool

This method tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
