Trait Implementations

impl<S: Clone> Clone for Stream<S>

fn clone(&self) -> Stream<S>

Returns a copy of the value.

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

Performs copy-assignment from source.

impl<S: Debug> Debug for Stream<S>

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

Formats the value using the given formatter.

impl<S> From<S> for Stream<S>

fn from(stream: S) -> Self

Performs the conversion.

impl<S: PartialEq> PartialEq<Stream<S>> for Stream<S>

fn eq(&self, other: &Stream<S>) -> bool

This method tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Stream<S>) -> bool

This method tests for !=.

impl<S> Positioned for Stream<S> where
    S: StreamOnce + Positioned,
    S::Token: PartialEq,
    S::Range: PartialEq, 

fn position(&self) -> S::Position

Returns the current position of the stream.

impl<S> RangeStreamOnce for Stream<S> where
    S: RangeStream,
    S::Token: PartialEq,
    S::Range: PartialEq, 

fn uncons_range(
    &mut self,
    size: usize
) -> Result<Self::Range, StreamErrorFor<Self>>

Takes size elements from the stream. Fails if the length of the stream is less than size.

fn uncons_while<F>(&mut self, f: F) -> Result<Self::Range, StreamErrorFor<Self>> where
    F: FnMut(Self::Token) -> bool, 

Takes items from stream, testing each one with predicate. returns the range of items which passed predicate.

fn uncons_while1<F>(
    &mut self,
    f: F
) -> ParseResult<Self::Range, StreamErrorFor<Self>> where
    F: FnMut(Self::Token) -> bool, 

Takes items from stream, testing each one with predicate returns a range of at least one items which passed predicate.

fn distance(&self, end: &Self::Checkpoint) -> usize

Returns the distance between self and end. The returned usize must be so that

fn range(&self) -> Self::Range

Returns the entire range of self

impl<S> ResetStream for Stream<S> where
    S: ResetStream + Positioned,
    S::Token: PartialEq,
    S::Range: PartialEq, 

type Checkpoint = S::Checkpoint

fn checkpoint(&self) -> Self::Checkpoint

Creates a Checkpoint at the current position which can be used to reset the stream later to the current position

fn reset(&mut self, checkpoint: Self::Checkpoint) -> Result<(), Self::Error>

Attempts to reset the stream to an earlier position.

impl<S> StreamOnce for Stream<S> where
    S: StreamOnce + Positioned,
    S::Token: PartialEq,
    S::Range: PartialEq, 

type Token = S::Token

The type of items which is yielded from this stream.

type Range = S::Range

The type of a range of items yielded from this stream. Types which do not a have a way of yielding ranges of items should just use the Self::Token for this type.

type Position = S::Position

Type which represents the position in a stream. Ord is required to allow parsers to determine which of two positions are further ahead.

type Error = ParseError<S>

fn uncons(&mut self) -> Result<Self::Token, StreamErrorFor<Self>>

Takes a stream and removes its first token, yielding the token and the rest of the elements. Returns Err if no element could be retrieved.

fn is_partial(&self) -> bool

Returns true if this stream only contains partial input.
