Struct ErrorNode 

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

Wrapper for unrecognized / malformed top-level content (PR 2.4 ERROR_NODE). Typed-AST consumers can use this to surface error regions to users (e.g., LSP diagnostics).

Implementations

impl ErrorNode

pub fn text(&self) -> SyntaxText

The raw bytes of the malformed region as a SyntaxText rope view. Zero allocation; use .to_string() on the result if you need an owned String, or format! / Display for direct output.

Trait Implementations

impl AstNode for ErrorNode

fn can_cast(kind: SyntaxKind) -> bool

Returns true iff kind is the wrapper’s expected node kind. Used by cast and by enum dispatch.

fn cast(syntax: SyntaxNode) -> Option<Self>

Wrap syntax if its kind matches; otherwise None.

fn syntax(&self) -> &SyntaxNode

The underlying CST node. text() reproduces the original bytes; children() / children_with_tokens() walk the tree.

impl Clone for ErrorNode

fn clone(&self) -> ErrorNode

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ErrorNode

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

Formats the value using the given formatter.

impl Eq for ErrorNode

impl Hash for ErrorNode

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 ErrorNode

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