Used to represent nodes such as tokens or function definitions

This trait is sealed and cannot be implemented for types outside of full-moon

Required methods

fn start_position(&self) -> Option<Position>

The start position of a node. None if can't be determined

fn end_position(&self) -> Option<Position>

The end position of a node. None if it can't be determined

fn similar(&self, other: &Self) -> bool where
    Self: Sized, 

Whether another node of the same type is the same as this one semantically, ignoring position

fn tokens<'b>(&'b self) -> Tokens<'ast, 'b>ⓘ

Important traits for Tokens<'ast, 'b>

impl<'ast, 'b> Iterator for Tokens<'ast, 'b> type Item = Cow<'b, TokenReference<'ast>>;

The token references that comprise a node

Provided methods

fn range(&self) -> Option<(Position, Position)>

The full range of a node, if it has both start and end positions

fn surrounding_trivia<'b>(
    &'b self
) -> (Vec<Cow<'b, Token<'ast>>>, Vec<Cow<'b, Token<'ast>>>)

The tokens surrounding a node that are ignored and not accessible through the node's own accessors. Use this if you want to get surrounding comments or whitespace. Returns a tuple of the leading and trailing trivia.
