Struct NodeId 

pub struct NodeId(/* private fields */);

Stable, unique identifier for AST nodes.

Each NodeId is globally unique within a process lifetime. Used for node identification, reference resolution, and diff comparison.

Implementations

impl NodeId

pub fn new() -> Self

Create a new unique NodeId.

pub fn from_raw(value: u64) -> Self

Create a NodeId from a raw value. Used by arenas that manage their own ID allocation.

pub fn value(self) -> u64

Returns the raw numeric value of this ID.

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 Debug for NodeId

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

Formats the value using the given formatter.

impl Default for NodeId

fn default() -> Self

Returns the “default value” for a type.

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.

impl Serialize for NodeId

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

where __S: Serializer,

Serialize this value into the given Serde serializer.
