Methods
impl Token
[src]
pub fn from_ast_ident(ident: Ident) -> Token
[src]
Recovers a Token
from an ast::Ident
. This creates a raw identifier if necessary.
pub fn can_begin_const_arg(&self) -> bool
[src]
Returns true
if the token can appear at the start of a const param.
pub fn ident(&self) -> Option<(Ident, bool)>
[src]
Returns an identifier if this token is an identifier.
pub fn lifetime(&self) -> Option<Ident>
[src]
Returns a lifetime identifier if this token is a lifetime.
pub fn is_ident(&self) -> bool
[src]
Returns true
if the token is an identifier.
pub fn is_keyword(&self, kw: Keyword) -> bool
[src]
Returns true
if the token is a given keyword, kw
.
pub fn is_path_segment_keyword(&self) -> bool
[src]
pub fn is_special_ident(&self) -> bool
[src]
pub fn is_reserved_ident(&self) -> bool
[src]
Returns true
if the token is either a special identifier or a keyword.
