Struct VarDecl 

pub struct VarDecl { /* private fields */ }

Implementations

impl VarDecl

pub fn name_token(&self) -> Option<SyntaxToken>

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

The initializer expression’s root node, if the = clause was present. var name = expr always parses the initializer as exactly one child node (whatever expression-grammar kind it is) after the IDENT, so “the first child node that is neither the leading doc comment nor the : type annotation” is unambiguous.

pub fn type_annotation(&self) -> Option<TypeAnnotation>

The binding’s : type annotation, if written (NG-B, #1488).

pub fn doc(&self) -> Option<DocComment>

The leading /// doc comment, if one is attached (B0.6b).

pub fn is_pub(&self) -> bool

See FlowDecl::is_pub.
