Implementations

impl Ident

pub const DUMMY: Ident

A dummy identifier.

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

Constructs a new identifier from a symbol and a span.

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

Constructs a new identifier with a dummy span.

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

Maps a string to an identifier with a dummy span.

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

Maps a string and a span to an identifier.

pub fn to_string(&self) -> String

“Specialization” of ToString using as_str.

pub fn as_str(&self) -> &str

Access the underlying string.

Note that the lifetime of the return value is a lie. See Symbol::as_str() for details.

pub fn as_str_in(self, session: &Session) -> &str

Access the underlying string in the given session.

The identifier must have been interned in the given session.

pub fn is_used_keyword(self) -> bool

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

pub fn is_unused_keyword(self) -> bool

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

pub fn is_weak_keyword(self) -> bool

Returns true if the identifier is a weak keyword and can be used in variable names.

pub fn is_yul_keyword(self) -> bool

Returns true if the identifier is a keyword in a Yul context.

pub fn is_yul_evm_builtin(self) -> bool

Returns true if the identifier is a Yul EVM builtin keyword.

pub fn is_reserved(self, yul: bool) -> bool

Returns true if the identifier is either a keyword, either currently in use or reserved for possible future use.

pub fn is_non_reserved(self, yul: bool) -> bool

Returns true if the identifier is not a reserved keyword. See is_reserved.

pub fn is_elementary_type(self) -> bool

Returns true if the identifier is an elementary type name.

Note that this does not include [u]fixedMxN types.

pub fn is_bool_lit(self) -> bool

Returns true if the identifier is true or false.

pub fn is_location_specifier(self) -> bool

Returns true if the identifier is a location specifier.

pub fn is_mutability_specifier(self) -> bool

Returns true if the identifier is a mutability specifier.

pub fn is_visibility_specifier(self) -> bool

Returns true if the identifier is a visibility specifier.
