Implementations§

source§

impl<L: Language> SyntaxToken<L>

source

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

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

source

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

source

pub fn text_range(&self) -> TextRange

source

pub fn index(&self) -> usize

source

pub fn text(&self) -> &str

source

pub fn green(&self) -> &GreenTokenData

source

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

source

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

👎Deprecated: use SyntaxToken::parent_ancestors instead

Iterator over all the ancestors of this token excluding itself.

source

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

Iterator over all the ancestors of this token excluding itself.

source

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

source

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

source

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

source

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

Next token in the tree (i.e, not necessary a sibling).

source

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

Previous token in the tree (i.e, not necessary a sibling).

source

pub fn detach(&self)
