Struct NodeId 

pub struct NodeId(pub u32);

Stable identifier assigned to every Node at parse time.

Used as the key in side-tables maintained by relon-analyzer (resolved references, desugar caches, diagnostics) so analyzer passes can attach information without mutating the AST itself.

Tuple Fields

0: u32

Implementations

impl NodeId

pub const SYNTHETIC: NodeId

Sentinel id for synthetic nodes built outside the parser (e.g. by the evaluator when fabricating a Type node mid-flight). Analyzer side-tables must not key on this value.

pub fn alloc() -> NodeId

Allocate a fresh, process-wide-unique id.

Public so AST rewriters outside the parser (analyzer, evaluator fabricated nodes, host transforms) can mint ids that won’t collide with parser-emitted ones.

Trait Implementations

impl Clone for NodeId

fn clone(&self) -> NodeId

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for NodeId

impl Debug for NodeId

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

Formats the value using the given formatter.

impl Default for NodeId

fn default() -> NodeId

Returns the “default value” for a type.

impl Eq for NodeId

impl Hash for NodeId

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 for NodeId

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