Implementations

impl<I: Iterator> Timeline<I>

pub fn new(iter: I) -> Self

pub fn iter(&self) -> TimelineIter<'_, I>

pub fn now_len(&self) -> usize

Number of history records currently stored

pub fn next(&mut self) -> Option<&I::Item>

pub fn to_end(&mut self)

Iterate internal iterator to completion

pub fn is_end(&self) -> bool

Check if the internal iterator has been completed

pub fn get(&mut self, index: usize) -> Option<&I::Item>

Get the value of the specified position

• None if the internal iterator is completed but not found
• None if index is less than 0

Trait Implementations

impl<I: Iterator> Clone for Timeline<I>

fn clone(&self) -> Self

Returns a copy of the value.

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

Performs copy-assignment from source.

impl<I: Iterator> Debug for Timeline<I>

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

Formats the value using the given formatter.

impl<I> Default for Timeline<I>where I: Default + Iterator, I::Item: Default,

fn default() -> Self

Returns the “default value” for a type.

impl<I: Iterator> From<Rc<ExtRefCell<TimelineBox<I>>>> for Timeline<I>

fn from(inner: Rc<ExtRefCell<TimelineBox<I>>>) -> Self

Converts to this type from the input type.

impl<I: Iterator> Hash for Timeline<I>

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<I: Iterator> Index<Range<usize>> for Timeline<I>

type Output = [<I as Iterator>::Item]

The returned type after indexing.

fn index(&self, index: Range<usize>) -> &Self::Output

Performs the indexing (container[index]) operation.

impl<I: Iterator> Index<RangeFrom<usize>> for Timeline<I>

type Output = [<I as Iterator>::Item]

The returned type after indexing.

fn index(&self, index: RangeFrom<usize>) -> &Self::Output

Performs the indexing (container[index]) operation.

impl<I: Iterator> Index<RangeFull> for Timeline<I>

type Output = [<I as Iterator>::Item]

The returned type after indexing.

fn index(&self, index: RangeFull) -> &Self::Output

Performs the indexing (container[index]) operation.

impl<I: Iterator> Index<RangeTo<usize>> for Timeline<I>

type Output = [<I as Iterator>::Item]

The returned type after indexing.

fn index(&self, index: RangeTo<usize>) -> &Self::Output

Performs the indexing (container[index]) operation.

impl<I: Iterator> Index<usize> for Timeline<I>

type Output = <I as Iterator>::Item

The returned type after indexing.

fn index(&self, index: usize) -> &Self::Output

Performs the indexing (container[index]) operation.

impl<I: Iterator> PartialEq for Timeline<I>

fn eq(&self, other: &Self) -> bool

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

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

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

impl<I: Iterator> RefClone for Timeline<I>

fn ref_clone(&self) -> Self

Clone a shared reference
