Trait Implementations

impl<S: Clone, U: Clone> Clone for Stream<S, U>

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

Returns a copy of the value.

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

Performs copy-assignment from source.

impl<S: Debug, U: Debug> Debug for Stream<S, U>

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

Formats the value using the given formatter.

impl<S: Ord, U: Ord> Ord for Stream<S, U>

fn cmp(&self, other: &Stream<S, U>) -> 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<S: PartialEq, U: PartialEq> PartialEq for Stream<S, U>

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

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

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<S: PartialOrd, U: PartialOrd> PartialOrd for Stream<S, U>

fn partial_cmp(&self, other: &Stream<S, U>) -> 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<S, U> Positioned for Stream<S, U>

where S: Positioned,

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

Returns the current position of the stream.

impl<S, U> RangeStreamOnce for Stream<S, U>

where S: RangeStreamOnce,

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, U> ResetStream for Stream<S, U>

where S: ResetStream,

type Checkpoint = <S as ResetStream>::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, U> StreamOnce for Stream<S, U>

where S: StreamOnce,

type Token = <S as StreamOnce>::Token

The type of items which is yielded from this stream.

type Range = <S as StreamOnce>::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 as StreamOnce>::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 = <S as StreamOnce>::Error

fn uncons(&mut self) -> Result<S::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.
