Struct cairo_lang_syntax::node::SyntaxNode

pub struct SyntaxNode(_);

SyntaxNode. Untyped view of the syntax tree. Adds parent() and offset() capabilities.

Implementations

impl SyntaxNode

pub fn new_root(db: &dyn SyntaxGroup, green: SyntaxFileGreen) -> Self

pub fn offset(&self) -> TextOffset

pub fn width(&self, db: &dyn SyntaxGroup) -> u32

pub fn kind(&self, db: &dyn SyntaxGroup) -> SyntaxKind

pub fn span(&self, db: &dyn SyntaxGroup) -> TextSpan

pub fn text(&self, db: &dyn SyntaxGroup) -> Option<SmolStr>

Returns the text of the token if this node is a token.

pub fn green_node(&self, db: &dyn SyntaxGroup) -> GreenNode

pub fn span_without_trivia(&self, db: &dyn SyntaxGroup) -> TextSpan

pub fn children<'db>(
    &self,
    db: &'db dyn SyntaxGroup
) -> SyntaxNodeChildIterator<'db>

pub fn parent(&self) -> Option<SyntaxNode>

pub fn stable_ptr(&self) -> SyntaxStablePtrId

pub fn lookup_ptr(
    &self,
    db: &dyn SyntaxGroup,
    stable_ptr: SyntaxStablePtrId
) -> SyntaxNode

Lookups a syntax node using a stable syntax pointer. Should only be called on the root from which the stable pointer was generated.

pub fn get_terminal_token(&self, db: &dyn SyntaxGroup) -> Option<SyntaxNode>

Gets the inner token from a terminal SyntaxNode. If the given node is not a terminal, returns None.

pub fn span_start_without_trivia(&self, db: &dyn SyntaxGroup) -> TextOffset

pub fn span_end_without_trivia(&self, db: &dyn SyntaxGroup) -> TextOffset

pub fn lookup_offset(
    &self,
    db: &dyn SyntaxGroup,
    offset: TextOffset
) -> SyntaxNode

Lookups a syntax node using an offset.

pub fn get_text(&self, db: &dyn SyntaxGroup) -> String

Returns all the text under the syntax node. Note that this traverses the syntax tree, and generates a new string, so use responsibly.

pub fn get_text_without_trivia(self, db: &dyn SyntaxGroup) -> String

Returns all the text under the syntax node, without the outmost trivia (the leading trivia of the first token and the trailing trivia of the last token).

Note that this traverses the syntax tree, and generates a new string, so use responsibly.

pub fn get_text_of_span(self, db: &dyn SyntaxGroup, span: TextSpan) -> String

Returns the text under the syntax node, according to the given span.

span is assumed to be contained within the span of self.

Note that this traverses the syntax tree, and generates a new string, so use responsibly.

Trait Implementations

impl Clone for SyntaxNode

fn clone(&self) -> SyntaxNode

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for SyntaxNode

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

Formats the value using the given formatter.

impl Hash for SyntaxNode

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<SyntaxNode> for SyntaxNode

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

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

fn ne(&self, other: &Rhs) -> bool

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
