Struct AnyNodeTag 

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

Type-erased AST node tag represented as a raw ordinal.

Use this for grammar-agnostic AST introspection.

Implementations

impl AnyNodeTag

pub fn from_raw(v: u32) -> Self

Construct from a raw node tag ordinal.

This does not validate that v is a known tag for any particular grammar. Prefer typed tags when available.

Trait Implementations

impl Clone for AnyNodeTag

fn clone(&self) -> AnyNodeTag

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for AnyNodeTag

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

Formats the value using the given formatter.

impl From<AnyNodeTag> for u32

fn from(t: AnyNodeTag) -> u32

Converts to this type from the input type.

impl From<NodeTag> for AnyNodeTag

fn from(t: NodeTag) -> AnyNodeTag

Converts to this type from the input type.

impl Hash for AnyNodeTag

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 AnyNodeTag

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