Struct ParserStream

pub struct ParserStream<'input, 'parser, In: ?Sized, Out, Err, P: Parser<In, Out, Err>> { /* private fields */ }

A Stream which wraps a Parser and its input.

Calling Stream::next will call the Parser::parse method of the wrapped Parser, with the input that the ParserStream was initialized with.

Implementations

impl<'input, 'parser, In: ?Sized, Out, Err, P: Parser<In, Out, Err>> ParserStream<'input, 'parser, In, Out, Err, P>

pub fn new(input: &'input mut In, parser: &'parser mut P) -> Self

Creates a new ParserStream from the provided input and Parser.

Trait Implementations

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

Formats the value using the given formatter.

impl<'input, 'parser, In: Hash + ?Sized, Out: Hash, Err: Hash, P: Hash + Parser<In, Out, Err>> Hash for ParserStream<'input, 'parser, In, Out, Err, P>

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl<'input, 'parser, In: Ord + ?Sized, Out: Ord, Err: Ord, P: Ord + Parser<In, Out, Err>> Ord for ParserStream<'input, 'parser, In, Out, Err, P>

fn cmp( &self, other: &ParserStream<'input, 'parser, In, Out, Err, P>, ) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Self

where Self: Sized,

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Self

where Self: Sized,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Self

where Self: Sized,

Restrict a value to a certain interval.

impl<'input, 'parser, In: PartialEq + ?Sized, Out: PartialEq, Err: PartialEq, P: PartialEq + Parser<In, Out, Err>> PartialEq for ParserStream<'input, 'parser, In, Out, Err, P>

fn eq(&self, other: &ParserStream<'input, 'parser, In, Out, Err, P>) -> bool

Tests for self and other values to be equal, and is used by ==.

const fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl<'input, 'parser, In: PartialOrd + ?Sized, Out: PartialOrd, Err: PartialOrd, P: PartialOrd + Parser<In, Out, Err>> PartialOrd for ParserStream<'input, 'parser, In, Out, Err, P>

fn partial_cmp( &self, other: &ParserStream<'input, 'parser, In, Out, Err, P>, ) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

fn lt(&self, other: &Rhs) -> bool

Tests less than (for self and other) and is used by the < operator.

fn le(&self, other: &Rhs) -> bool

Tests less than or equal to (for self and other) and is used by the <= operator.

fn gt(&self, other: &Rhs) -> bool

Tests greater than (for self and other) and is used by the > operator.

fn ge(&self, other: &Rhs) -> bool

Tests greater than or equal to (for self and other) and is used by the >= operator.

impl<'input, 'parser, In: ?Sized, Out, Err, P: Parser<In, Out, Err>> Stream for ParserStream<'input, 'parser, In, Out, Err, P>

type Item = Out

The type of the items returned by the Stream if no error occurs.

type Error = Err

The type of error that may occur while iterating.

fn next(&mut self) -> Result<Self::Item, Self::Error>

Returns the next item in the stream, or an error if one occurs.
