Tuple Fields

0: Group

Trait Implementations

impl Clone for NoneGroup

fn clone(&self) -> NoneGroup

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for NoneGroup

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

Formats the value using the given formatter.

impl From<NoneGroup> for Group

fn from(group: NoneGroup) -> Self

Converts to this type from the input type.

impl From<NoneGroup> for TokenTree

fn from(group: NoneGroup) -> Self

Converts to this type from the input type.

impl GroupDelimiter for NoneGroup

fn delimiter(&self) -> Delimiter

The surrounding Delimiter of the group.

impl Parser for NoneGroup

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 NoneGroup

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

Write &self to the given TokenStream.

fn to_token_iter(&self) -> TokenIter

Convert &self into a TokenIter object.

fn into_token_iter(self) -> TokenIter

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.
