Struct Macros20NormalizedIdent 

pub struct Macros20NormalizedIdent(pub Ident);

An newtype around Ident that calls Ident::normalize_to_macros_2_0 on construction for “item hygiene” comparisons.

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.

Tuple Fields

0: Ident

Implementations

impl Macros20NormalizedIdent

pub fn new(ident: Ident) -> Self

pub fn with_dummy_span(name: Symbol) -> Self

Methods from Deref<Target = Ident>

pub fn as_str(&self) -> &str

Access the underlying string. This is a slowish operation because it requires locking the symbol interner.

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

Trait Implementations

impl Clone for Macros20NormalizedIdent

fn clone(&self) -> Macros20NormalizedIdent

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Macros20NormalizedIdent

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

Formats the value using the given formatter.

impl Deref for Macros20NormalizedIdent

By impl Deref, we can access the wrapped Ident as if it were a normal Ident such as norm_ident.name instead of norm_ident.0.name.

type Target = Ident

The resulting type after dereferencing.

fn deref(&self) -> &Self::Target

Dereferences the value.

impl Display for Macros20NormalizedIdent

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

Formats the value using the given formatter.

impl Hash for Macros20NormalizedIdent

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

Feeds this value into the given Hasher.

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

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl PartialEq for Macros20NormalizedIdent

fn eq(&self, other: &Macros20NormalizedIdent) -> bool

Tests for self and other values to be equal, and is used by ==.

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

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl Copy for Macros20NormalizedIdent

impl Eq for Macros20NormalizedIdent

impl StructuralPartialEq for Macros20NormalizedIdent

Layout

Note: Most layout information is completely unstable and may even differ between compilations. The only exception is types with certain repr(...) attributes. Please see the Rust Reference's “Type Layout” chapter for details on type layout guarantees.
