Struct joinery::iter::JoinIter [−][src]
#[must_use]pub struct JoinIter<Iter: Iterator, Sep> { /* fields omitted */ }
Expand description
An iterator for a Join
.
Emits the elements of the Join
’s underlying iterator, interspersed with
its separator. Note that it uses clone
to generate copies
of the separator while iterating, but also keep in mind that in most cases
the JoinItem
instance will have a trivially cloneable separator, such
as &
str
or char
.
Examples
Via IntoIterator
:
use joinery::{Joinable, JoinItem}; let join = vec![1, 2, 3].join_with(" "); let mut join_iter = join.into_iter(); assert_eq!(join_iter.next(), Some(JoinItem::Element(1))); assert_eq!(join_iter.next(), Some(JoinItem::Separator(" "))); assert_eq!(join_iter.next(), Some(JoinItem::Element(2))); assert_eq!(join_iter.next(), Some(JoinItem::Separator(" "))); assert_eq!(join_iter.next(), Some(JoinItem::Element(3))); assert_eq!(join_iter.next(), None);
Via iter_join_with
:
use joinery::{JoinableIterator, JoinItem}; let mut iter = (0..6) .filter(|x| x % 2 == 0) .map(|x| x * 2) .iter_join_with(", "); assert_eq!(iter.next(), Some(JoinItem::Element(0))); assert_eq!(iter.next(), Some(JoinItem::Separator(", "))); assert_eq!(iter.next(), Some(JoinItem::Element(4))); assert_eq!(iter.next(), Some(JoinItem::Separator(", "))); assert_eq!(iter.next(), Some(JoinItem::Element(8))); assert_eq!(iter.next(), None);
Implementations
impl<I: Iterator, S> JoinIter<I, S>
[src]
impl<I: Iterator, S> JoinIter<I, S>
[src]pub fn is_sep_next(&self) -> bool
[src]
pub fn is_sep_next(&self) -> bool
[src]Check if the next iteration of this iterator will (try to) return a
separator. Note that this does not check if the underlying iterator is
empty, so the next next
call could still return None
.
Examples
use joinery::{JoinableIterator, JoinItem}; let mut join_iter = (0..3).join_with(", ").into_iter(); assert_eq!(join_iter.is_sep_next(), false); join_iter.next(); assert_eq!(join_iter.is_sep_next(), true); join_iter.next(); assert_eq!(join_iter.is_sep_next(), false);
pub fn peek(&mut self) -> Option<JoinItem<&I::Item, &S>>
[src]
pub fn peek(&mut self) -> Option<JoinItem<&I::Item, &S>>
[src]Peek at what the next item in the iterator will be without consuming
it. Note that this interface is similar, but not identical, to
Peekable::peek
.
Examples
use joinery::{JoinableIterator, JoinItem}; let mut join_iter = (0..3).join_with(", ").into_iter(); assert_eq!(join_iter.peek(), Some(JoinItem::Element(&0))); assert_eq!(join_iter.next(), Some(JoinItem::Element(0))); assert_eq!(join_iter.peek(), Some(JoinItem::Separator(&", "))); assert_eq!(join_iter.next(), Some(JoinItem::Separator(", "))); assert_eq!(join_iter.peek(), Some(JoinItem::Element(&1))); assert_eq!(join_iter.next(), Some(JoinItem::Element(1)));
pub fn peek_element(&mut self) -> Option<&I::Item>
[src]
pub fn peek_element(&mut self) -> Option<&I::Item>
[src]Peek at what the next non-separator item in the iterator will be without consuming it.
Examples
use joinery::{Joinable, JoinItem}; let mut join_iter = vec!["This", "is", "a", "sentence"].join_with(' ').into_iter(); assert_eq!(join_iter.peek_element(), Some(&"This")); assert_eq!(join_iter.peek(), Some(JoinItem::Element(&"This"))); assert_eq!(join_iter.next(), Some(JoinItem::Element("This"))); assert_eq!(join_iter.peek_element(), Some(&"is")); assert_eq!(join_iter.peek(), Some(JoinItem::Separator(&' '))); assert_eq!(join_iter.next(), Some(JoinItem::Separator(' '))); assert_eq!(join_iter.peek_element(), Some(&"is")); assert_eq!(join_iter.peek(), Some(JoinItem::Element(&"is"))); assert_eq!(join_iter.next(), Some(JoinItem::Element("is")));

fn join_with<S>(self, sep: S) -> Join<CloneIterator<Self>, S> where
Self: Clone,
[src]Convert a cloneable iterator into a Join
instance. Whenever the Join
needs to immutabley iterate over the underlying iterator (for instance, when
formatting it with Display
), the underlying iterator is cloned. For most
iterator types this is a cheap operation, because the iterator contains just
a reference to the underlying collection. Read more
