Struct DelimitedVec 

pub struct DelimitedVec<T, D>(pub Vec<Delimited<T, D>>);

Since the delimiter in Delimited<T,D> is optional a Vec<Delimited<T,D>> would parse consecutive values even without delimiters. DelimitedVec<T,D> will stop parsing after the first value without a delimiter.

Tuple Fields

0: Vec<Delimited<T, D>>

Trait Implementations

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

where T: Clone, D: Clone,

fn clone(&self) -> DelimitedVec<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 DelimitedVec<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> From<DelimitedVec<T, D>> for Vec<T>

Converts a DelimitedVec<T, D> into a Vec<T>. This loses all delimiters, which may have been stateful (Either or other enums).

fn from(delimited_vec: DelimitedVec<T, D>) -> Vec<T>

Converts to this type from the input type.

impl<T, D> IntoIterator for DelimitedVec<T, D>

type Item = Delimited<T, D>

The type of the elements being iterated over.

type IntoIter = IntoIter<<DelimitedVec<T, D> as IntoIterator>::Item>

Which kind of iterator are we turning this into?

fn into_iter(self) -> <DelimitedVec<T, D> as IntoIterator>::IntoIter

Creates an iterator from a value.

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

where T: Parse, D: Parse,

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

where T: Parse, D: Parse,

fn parse_repeats( tokens: &mut ShadowCountedIter<'_, <TokenStream as IntoIterator>::IntoIter>, min: usize, max: usize, ) -> Result<DelimitedVec<T, D>, Error>

Parse at least min and up to max (inclusive) elements.

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

Parse any number of elements.

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

Parse at least one element.

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

Parse zero or one element.

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

Parse exactly n elements.

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

Parse at most n elements.

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

Parse at least n elements.

impl<T, D> ToTokens for DelimitedVec<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.
