pub struct SyntaxNode<L: Language> { /* fields omitted */ }

Implementations

impl<L: Language> SyntaxNode<L>

pub fn new_root(green: GreenNode) -> SyntaxNode<L>

pub fn replace_with(&self, replacement: GreenNode) -> GreenNode

Returns a green tree, equal to the green tree this node belongs two, except with this node substitute. The complexity of operation is proportional to the depth of the tree

pub fn kind(&self) -> L::Kind

pub fn text_range(&self) -> TextRange

pub fn index(&self) -> usize

pub fn text(&self) -> SyntaxText

pub fn green(&self) -> Cow<'_, GreenNodeData>

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

pub fn ancestors(&self) -> impl Iterator<Item = SyntaxNode<L>>

pub fn children(&self) -> SyntaxNodeChildren<L>

pub fn children_with_tokens(&self) -> SyntaxElementChildren<L>

pub fn first_child(&self) -> Option<SyntaxNode<L>>

pub fn last_child(&self) -> Option<SyntaxNode<L>>

pub fn first_child_or_token(&self) -> Option<SyntaxElement<L>>

pub fn last_child_or_token(&self) -> Option<SyntaxElement<L>>

pub fn next_sibling(&self) -> Option<SyntaxNode<L>>

pub fn prev_sibling(&self) -> Option<SyntaxNode<L>>

pub fn next_sibling_or_token(&self) -> Option<SyntaxElement<L>>

pub fn prev_sibling_or_token(&self) -> Option<SyntaxElement<L>>

pub fn first_token(&self) -> Option<SyntaxToken<L>>

Return the leftmost token in the subtree of this node.

pub fn last_token(&self) -> Option<SyntaxToken<L>>

Return the rightmost token in the subtree of this node.

pub fn siblings(
    &self,
    direction: Direction
) -> impl Iterator<Item = SyntaxNode<L>>

pub fn siblings_with_tokens(
    &self,
    direction: Direction
) -> impl Iterator<Item = SyntaxElement<L>>

pub fn descendants(&self) -> impl Iterator<Item = SyntaxNode<L>>

pub fn descendants_with_tokens(&self) -> impl Iterator<Item = SyntaxElement<L>>

pub fn preorder(&self) -> Preorder<L>

Traverse the subtree rooted at the current node (including the current node) in preorder, excluding tokens.

pub fn preorder_with_tokens(
    &self
) -> impl Iterator<Item = WalkEvent<SyntaxElement<L>>>

Traverse the subtree rooted at the current node (including the current node) in preorder, including tokens.

pub fn token_at_offset(&self, offset: TextSize) -> TokenAtOffset<SyntaxToken<L>>

Find a token in the subtree corresponding to this node, which covers the offset. Precondition: offset must be withing node’s range.

pub fn covering_element(&self, range: TextRange) -> SyntaxElement<L>

Return the deepest node or token in the current subtree that fully contains the range. If the range is empty and is contained in two leaf nodes, either one can be returned. Precondition: range must be contained withing the current node

pub fn child_or_token_at_range(
    &self,
    range: TextRange
) -> Option<SyntaxElement<L>>

Finds a SyntaxElement which intersects with a given range. If there are several intersecting elements, any one can be returned.

The method uses binary search internally, so it’s complexity is O(log(N)) where N = self.children_with_tokens().count().

pub fn clone_subtree(&self) -> SyntaxNode<L>

Returns an independent copy of the subtree rooted at this node.

The parent of the returned node will be None, the start offset will be zero, but, otherwise, it’ll be equivalent to the source node.

pub fn clone_for_update(&self) -> SyntaxNode<L>

pub fn detach(&self)

pub fn splice_children(
    &self,
    to_delete: Range<usize>,
    to_insert: Vec<SyntaxElement<L>>
)
