Enum TokenTree 

pub enum TokenTree {
    Token(TokenTreeToken),
    Block(TokenTreeBlock),
}

A token tree node - either a single token or a delimited group

Variants

Token(TokenTreeToken)

A single token

Block(TokenTreeBlock)

A delimited group of token trees

Implementations

impl TokenTree

Trait Implementations

impl Debug for TokenTree

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Display for TokenTree

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl PartialEq for TokenTree

fn eq(&self, other: &TokenTree) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
