Struct Delimited 

pub struct Delimited<T, D> {
    pub value: T,
    pub delimiter: Option<D>,
}

This is used when one wants to parse a list of entities separated by delimiters. The delimiter is optional and can be None eg. when the entity is the last in the list. Usually the delimiter will be some simple punctuation token, but it is not limited to that.

Fields

value: T

The parsed value

delimiter: Option<D>

The optional delimiter

Trait Implementations

impl<T, D> Clone for Delimited<T, D>

where T: Clone, D: Clone,

fn clone(&self) -> Delimited<T, D>

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl<T, D> Debug for Delimited<T, D>

where T: Debug, D: Debug,

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

Formats the value using the given formatter.

impl<T, D> Parser for Delimited<T, D>

where T: Parse, D: Parse,

fn parser( tokens: &mut ShadowCountedIter<'_, <TokenStream as IntoIterator>::IntoIter>, ) -> Result<Delimited<T, D>, 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<T, D> ToTokens for Delimited<T, D>

where T: ToTokens, D: 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.
