An AST node.

Required methods

fn id(&self) -> NodeId

Get this node's unique ID.

fn span(&self) -> Span

Get this node's span in the input.

fn order(&self) -> usize

Get this node's lexical order.

Provided methods

fn human_span(&self) -> Span

Get a span that is terse and suitable to pinpoint the node for a human.

fn get_parent(&self) -> Option<&'a dyn AnyNode<'a>>

Get this node's parent.

fn link(&'a self, parent: Option<&'a dyn AnyNode<'a>>, order: &mut usize)

Link up this node.

fn link_attach(&'a self, parent: &'a dyn AnyNode<'a>, order: usize)

Link up this node as an expansion of another node.

All subnodes inherit the order from their parent. Useful if a node is generated as part of a later expansion/analysis pass, but needs to hook into the AST somewhere.

fn as_ptr(&self) -> *const u8

Convert this node reference to a pointer for identity comparisons.

Trait Implementations

impl<'a> Eq for &'a dyn AnyNode<'a>

impl<'a> Hash for &'a dyn AnyNode<'a>

fn hash<H: Hasher>(&self, h: &mut H)

Feeds this value into the given [Hasher].

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

impl<'a> PartialEq<&'a (dyn AnyNode<'a> + 'a)> for &'a dyn AnyNode<'a>

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

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

#[must_use]fn ne(&self, other: &Rhs) -> bool

This method tests for !=.
