Methods

impl Token

pub fn from_ast_ident(ident: Ident) -> Token

Recovers a Token from an ast::Ident. This creates a raw identifier if necessary.

pub fn can_begin_const_arg(&self) -> bool

Returns true if the token can appear at the start of a const param.

pub fn ident(&self) -> Option<(Ident, bool)>

Returns an identifier if this token is an identifier.

pub fn lifetime(&self) -> Option<Ident>

Returns a lifetime identifier if this token is a lifetime.

pub fn is_ident(&self) -> bool

Returns true if the token is an identifier.

pub fn is_keyword(&self, kw: Keyword) -> bool

Returns true if the token is a given keyword, kw.

pub fn is_path_segment_keyword(&self) -> bool

pub fn is_special_ident(&self) -> bool

pub fn is_reserved_ident(&self) -> bool

Returns true if the token is either a special identifier or a keyword.

Trait Implementations

impl From<Token> for TokenStream

fn from(token: Token) -> TokenStream

Performs the conversion.

impl Clone for Token

fn clone(&self) -> Token

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl PartialEq<Token> for Token

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

This method tests for self and other values to be equal, and is used by ==.

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

This method tests for !=.

impl Debug for Token

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

Formats the value using the given formatter.

impl Encodable for Token

fn encode<__S: Encoder>(&self, s: &mut __S) -> Result<(), __S::Error>

impl Decodable for Token

fn decode<__D: Decoder>(d: &mut __D) -> Result<Token, __D::Error>
