Enum Element 

pub enum Element<N = SyntaxNode<WorkflowDescriptionLanguage>>
where
    N: TreeNode,
{
    Node(Node<N>),
    Token(Token<<N as TreeNode>::Token>),
}

An abstract syntax tree element.

Variants

Node(Node<N>)

An abstract syntax tree node.

Token(Token<<N as TreeNode>::Token>)

An abstract syntax tree token.

Implementations

impl<N> Element<N>

where N: TreeNode,

pub fn as_node(&self) -> Option<&Node<N>>

Attempts to get a reference to the inner Node.

• If self is a Element::Node, then a reference to the inner Node wrapped in Some is returned.
• Else, None is returned.

pub fn into_node(self) -> Option<Node<N>>

Consumes self and attempts to return the inner Node.

• If self is a Element::Node, then the inner Node wrapped in Some is returned.
• Else, None is returned.

pub fn unwrap_node(self) -> Node<N>

Consumes self and returns the inner Node.

Panics

If self is not a Element::Node.

pub fn as_token(&self) -> Option<&Token<<N as TreeNode>::Token>>

Attempts to get a reference to the inner Token.

• If self is a Element::Token, then a reference to the inner Token wrapped in Some is returned.
• Else, None is returned.

pub fn into_token(self) -> Option<Token<<N as TreeNode>::Token>>

Consumes self and attempts to return the inner Token.

• If self is a Element::Token, then the inner Token wrapped in Some is returned.
• Else, None is returned.

pub fn unwrap_token(self) -> Token<<N as TreeNode>::Token>

Consumes self and returns the inner Token.

Panics

If self is not a Element::Token.

pub fn inner(&self) -> NodeOrToken<N, <N as TreeNode>::Token>

Gets the inner node or token from the Element.

pub fn kind(&self) -> SyntaxKind

Gets the underlying SyntaxKind from the Element.

pub fn is_trivia(&self) -> bool

Returns whether the Element represents trivia.

pub fn cast(element: NodeOrToken<N, <N as TreeNode>::Token>) -> Element<N>

Casts an element from a node or a token.
