Methods

impl Token

fn is_like_gt(&self) -> bool

Returns true if the token starts with '>'.

fn can_begin_expr(&self) -> bool

Returns true if the token can appear at the start of an expression.

fn is_lit(&self) -> bool

Returns true if the token is any literal

fn is_ident(&self) -> bool

Returns true if the token is an identifier.

fn is_path(&self) -> bool

Returns true if the token is an interpolated path.

fn is_plain_ident(&self) -> bool

Returns true if the token is a path that is not followed by a :: token.

fn is_lifetime(&self) -> bool

Returns true if the token is a lifetime.

fn is_mutability(&self) -> bool

Returns true if the token is either the mut or const keyword.

fn to_binop(&self) -> Option<BinOp_>

Maps a token to its corresponding binary operator.

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

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

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

fn is_any_keyword(&self) -> bool

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

fn is_strict_keyword(&self) -> bool

Returns true if the token may not appear as an identifier.

fn is_reserved_keyword(&self) -> bool

Returns true if the token is a keyword that has been reserved for possible future use.

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

Hygienic identifier equality comparison.

See styntax::ext::mtwt.

Trait Implementations

Derived Implementations

impl Debug for Token

fn fmt(&self, __arg_0: &mut Formatter) -> Result

Formats the value using the given formatter.

impl Hash for Token

fn hash<__H: Hasher>(&self, __arg_0: &mut __H)

Feeds this value into the state given, updating the hasher as necessary.

fn hash_slice<H>(data: &[Self], state: &mut H) where H: Hasher

Feeds a slice of this type into the state provided.

impl Eq for Token

impl PartialEq for Token

fn eq(&self, __arg_0: &Token) -> bool

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

fn ne(&self, __arg_0: &Token) -> bool
