Struct GroupContaining 

pub struct GroupContaining<C> {
    pub delimiter: Delimiter,
    pub content: C,
}

Any kind of Group G with parseable content C. The content C must parse exhaustive, a EndOfStream is automatically implied.

Fields

delimiter: Delimiter

The delimiters around the group.

content: C

The content of the group.

Implementations

impl<C> GroupContaining<C>

pub const fn new(delimiter: Delimiter, content: C) -> GroupContaining<C>

Create a new GroupContaining instance.

Example

let group = GroupContaining::new(
    Delimiter::Parenthesis,
    Literal::i32_unsuffixed(123),
);

Trait Implementations

impl<C> Clone for GroupContaining<C>

where C: Clone,

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

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl<C> Debug for GroupContaining<C>

where C: Debug,

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

Formats the value using the given formatter.

impl<C> From<GroupContaining<C>> for TokenTree

where C: ToTokens,

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

Converts to this type from the input type.

impl<C> GroupDelimiter for GroupContaining<C>

fn delimiter(&self) -> Delimiter

The surrounding Delimiter of the group.

impl<C> Parser for GroupContaining<C>

where C: Parse,

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