Struct proclet::PunctuatedParser

pub struct PunctuatedParser<T: TokenTree, M, D>(/* private fields */);

Parser for punctuated values.

Implementations

impl<T: TokenTreeExt, M: Parser<T>, D: Parser<T>> PunctuatedParser<T, M, D>

pub const fn new(main: M, delim: D) -> Self

Create a new PunctuatedParser using main as the parser for the main part and delim as the parser for the delimiter.

Trait Implementations

impl<T: Clone + TokenTree, M: Clone, D: Clone> Clone for PunctuatedParser<T, M, D>

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

Returns a copy of the value.

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

Performs copy-assignment from source.

impl<T: Debug + TokenTree, M: Debug, D: Debug> Debug for PunctuatedParser<T, M, D>

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

Formats the value using the given formatter.

impl<T: TokenTreeExt, M: Parser<T>, D: Parser<T>> Parser<T> for PunctuatedParser<T, M, D>

type Output<'p, 'b> = Punctuated<<M as Parser<T>>::Output<'p, 'b>, <D as Parser<T>>::Output<'p, 'b>> where Self: 'p

The output type of this parser.

fn parse<'p, 'b>( &'p self, buf: &mut &'b TokenBuf<T> ) -> Result<Self::Output<'p, 'b>, Error<T::Span>>

Parse a value from a TokenBuf using this parser.

fn parse_all<'p, 'b>( &'p self, buf: &mut &'b TokenBuf<T> ) -> Result<Self::Output<'p, 'b>, Error<T::Span>>

fn optional(self) -> Optional<Self>

where Self: Sized,

Wrap this parser in Optional to make it always succeed and return an option.
