Struct PunctAlone 

pub struct PunctAlone<const C: char>;

A single character punctuation token which is not followed by another punctuation character.

Example

let mut token_iter = ": :".to_token_iter();

let colon = PunctAlone::<':'>::parse(&mut token_iter).unwrap();
let colon = PunctAlone::<':'>::parse(&mut token_iter).unwrap();

Implementations

impl<const C: char> PunctAlone<C>

pub const fn new() -> PunctAlone<C>

Create a new PunctAlone object.

pub const fn as_char(&self) -> char

Get the char value this object represents.

Trait Implementations

impl<const C: char> Clone for PunctAlone<C>

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

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl<const C: char> Debug for PunctAlone<C>

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

Formats the value using the given formatter.

impl<const C: char> Default for PunctAlone<C>

fn default() -> PunctAlone<C>

Returns the “default value” for a type.

impl<const C: char> From<PunctAlone<C>> for TokenTree

Convert a PunctAlone object into a TokenTree.

fn from(_: PunctAlone<C>) -> TokenTree

Converts to this type from the input type.

impl<const C: char> Parser for PunctAlone<C>

fn parser( tokens: &mut ShadowCountedIter<'_, <TokenStream as IntoIterator>::IntoIter>, ) -> Result<PunctAlone<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<const C: char> ToTokens for PunctAlone<C>

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.
