Struct Attributes 

pub struct Attributes { /* private fields */ }

A Move attributes anottation.

Examples: #[test_only], #[allow(...)], doc comment (/// ...).

Implementations

impl Attributes

pub fn is_doc(&self) -> bool

Whether this is a #[doc = "..."].

pub const fn contents(&self) -> &impl ToTokens

Everything inside the bracket group, #[...].

pub fn erased_attributes(&self) -> impl Iterator<Item = &dyn ToTokens> + '_

Contents of each attribute.

pub fn external_attributes(&self) -> impl Iterator<Item = &dyn ToTokens> + '_

Contents of parameterized attributes as #[ext(<external_attribute>)]

Trait Implementations

impl Clone for Attributes

fn clone(&self) -> Attributes

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Attributes

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

Formats the value using the given formatter.

impl Parser for Attributes

fn parser(tokens: &mut TokenIter<'_>) -> Result<Self>

The actual parsing function that must be implemented. This mutates the tokens iterator directly. It should not be called from user code except for implementing parsers itself and then only when the rules below are followed.

impl ToTokens for Attributes

fn to_tokens(&self, tokens: &mut TokenStream)

Write &self to the given TokenStream.

fn to_token_iter( &self, ) -> ShadowCountedIter<'_, <TokenStream as IntoIterator>::IntoIter>

Convert &self into a TokenIter object.

fn into_token_iter<'a>( self, ) -> ShadowCountedIter<'a, <TokenStream as IntoIterator>::IntoIter>

where Self: Sized,

Convert self into a TokenIter object.

fn to_token_stream(&self) -> TokenStream

Convert &self into a TokenStream object.

fn into_token_stream(self) -> TokenStream

where Self: Sized,

Convert self into a TokenStream object.

fn tokens_to_string(&self) -> String

Convert &self into a String object. This is mostly used in the test suite to compare the outputs. When the input is a &str then this parses it and returns a normalized String.
