Implementations

impl Ident[src]

pub const fn new(name: Symbol, span: Span) -> Ident[src]

Constructs a new identifier from a symbol and a span.

pub const fn with_dummy_span(name: Symbol) -> Ident[src]

Constructs a new identifier with a dummy span.

pub fn invalid() -> Ident[src]

pub fn from_str(string: &str) -> Ident[src]

Maps a string to an identifier with a dummy span.

pub fn from_str_and_span(string: &str, span: Span) -> Ident[src]

Maps a string and a span to an identifier.

pub fn with_span_pos(self, span: Span) -> Ident[src]

Replaces lo and hi with those from span, but keep hygiene context.

pub fn without_first_quote(self) -> Ident[src]

pub fn normalize_to_macros_2_0(self) -> Ident[src]

"Normalize" ident for use in comparisons using "item hygiene". Identifiers with same string value become same if they came from the same macro 2.0 macro (e.g., macro item, but not macro_rules item) and stay different if they came from different macro 2.0 macros. Technically, this operation strips all non-opaque marks from ident's syntactic context.

pub fn normalize_to_macro_rules(self) -> Ident[src]

"Normalize" ident for use in comparisons using "local variable hygiene". Identifiers with same string value become same if they came from the same non-transparent macro (e.g., macro or macro_rules! items) and stay different if they came from different non-transparent macros. Technically, this operation strips all transparent marks from ident's syntactic context.

pub fn as_str(self) -> SymbolStr[src]

Convert the name to a SymbolStr. This is a slowish operation because it requires locking the symbol interner.

impl Ident[src]

pub fn is_special(self) -> bool[src]

pub fn is_used_keyword(self) -> bool[src]

Returns true if the token is a keyword used in the language.

pub fn is_unused_keyword(self) -> bool[src]

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

pub fn is_reserved(self) -> bool[src]

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

pub fn is_path_segment_keyword(self) -> bool[src]

A keyword or reserved identifier that can be used as a path segment.

pub fn is_raw_guess(self) -> bool[src]

We see this identifier in a normal identifier position, like variable name or a type. How was it written originally? Did it use the raw form? Let's try to guess.

impl Copy for Ident[src]

impl Debug for Ident[src]

impl<__D: Decoder> Decodable<__D> for Ident[src]

impl Display for Ident[src]

This implementation is supposed to be used in error messages, so it's expected to be identical to printing the original identifier token written in source code (token_to_string), except that AST identifiers don't keep the rawness flag, so we have to guess it.
