Struct NoneGroupContaining 

pub struct NoneGroupContaining<C> {
    pub content: C,
}

Parseable content within a None

Fields

content: C

The inner content of the group.

Implementations

impl<C> NoneGroupContaining<C>

pub const fn new(content: C) -> NoneGroupContaining<C>

create a new NoneGroupContaining instance

Trait Implementations

impl<C> Clone for NoneGroupContaining<C>

where C: Clone,

fn clone(&self) -> NoneGroupContaining<C>

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl<C> Debug for NoneGroupContaining<C>

where C: Debug,

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

Formats the value using the given formatter.

impl<C> From<NoneGroupContaining<C>> for TokenTree

where C: ToTokens,

fn from(group: NoneGroupContaining<C>) -> TokenTree

Converts to this type from the input type.

impl<C> GroupDelimiter for NoneGroupContaining<C>

fn delimiter(&self) -> Delimiter

The surrounding Delimiter of the group.

impl<C> Parser for NoneGroupContaining<C>

where C: Parse,

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

impl<C> ToTokens for NoneGroupContaining<C>

where C: ToTokens,

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.
