impl From<ParenthesisGroup> for Group

Source§

fn from(group: ParenthesisGroup) -> Group

Converts to this type from the input type.
Source§

impl From<ParenthesisGroup> for TokenTree

Source§

fn from(group: ParenthesisGroup) -> TokenTree

Converts to this type from the input type.
Source§

impl GroupDelimiter for ParenthesisGroup

Source§

fn delimiter(&self) -> Delimiter

The surrounding Delimiter of the group.
Source§

impl Parser for ParenthesisGroup

Source§

fn parser( tokens: &mut ShadowCountedIter<'_, <TokenStream as IntoIterator>::IntoIter>, ) -> Result<ParenthesisGroup, Error>

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. Read more
Source§

impl ToTokens for ParenthesisGroup

Source§

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

Write &self to the given TokenStream.
Source§

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

Convert &self into a TokenIter object.
Source§

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

Convert self into a TokenIter object.
Source§

fn to_token_stream(&self) -> TokenStream

Convert &self into a TokenStream object.
Source§

fn into_token_stream(self) -> TokenStream
where Self: Sized,

Convert self into a TokenStream object.
Source§

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.

where T: Parser,

Source§

fn parse( tokens: &mut ShadowCountedIter<'_, <TokenStream as IntoIterator>::IntoIter>, ) -> Result<Self, Error>
