pub struct SliceStream<'a, T>(pub &'a [T]);

Newtype for constructing a stream from a slice where the items in the slice are not copyable.

Tuple Fields

0: &'a [T]

Trait Implementations

impl<'a, T> Clone for SliceStream<'a, T>

fn clone(&self) -> SliceStream<'a, T>

Returns a copy of the value.

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

Performs copy-assignment from source.

impl<'a, T: Debug> Debug for SliceStream<'a, T>

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

Formats the value using the given formatter.

impl<'a, T> DefaultPositioned for SliceStream<'a, T>

type Positioner = IndexPositioner

impl<'a, T: Ord> Ord for SliceStream<'a, T>

fn cmp(&self, other: &SliceStream<'a, T>) -> 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<'a, T: PartialEq> PartialEq for SliceStream<'a, T>

fn eq(&self, other: &SliceStream<'a, T>) -> 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<'a, T: PartialOrd> PartialOrd for SliceStream<'a, T>

fn partial_cmp(&self, other: &SliceStream<'a, T>) -> 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<'a, T> Positioned for SliceStream<'a, T>

where T: PartialEq + 'a,

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

Returns the current position of the stream.

impl<'a, T> RangeStreamOnce for SliceStream<'a, T>

where T: PartialEq + 'a,

fn uncons_range(&mut self, size: usize) -> Result<&'a [T], 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<&'a [T], 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) -> 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<'a, T> ResetStream for SliceStream<'a, T>

where Self: StreamOnce,

type Checkpoint = SliceStream<'a, T>

fn checkpoint(&self) -> Self

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) -> Result<(), Self::Error>

Attempts to reset the stream to an earlier position.

impl<'a, T> StreamOnce for SliceStream<'a, T>

where T: PartialEq + 'a,

type Token = &'a T

The type of items which is yielded from this stream.

type Range = &'a [T]

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 = PointerOffset<[T]>

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 = UnexpectedParse

fn uncons(&mut self) -> Result<&'a T, 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.
