Struct rowan::SyntaxToken

pub struct SyntaxToken<'a> { /* fields omitted */ }

A token (leaf node) in a syntax tree.

A token can't exist in isolation, it is always attached to a parent Node.

Methods

impl<'a> SyntaxToken<'a>

pub fn kind(&self) -> SyntaxKind

Kind of this token.

pub fn text(&self) -> &'a SmolStr

Text of this token.

pub fn range(&self) -> TextRange

Text range, covered by this token.

pub fn parent(&self) -> &'a SyntaxNode

Parent node, containing this token.

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

Next sibling of this tokens, including both nodes and tokens.

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

Previous sibling of this tokens, including both nodes and tokens.

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

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

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

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

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

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