Expand description
Format all iterator elements lazily, separated by sep
.
The format value can only be formatted once, after that the iterator is exhausted.
See .format()
for more information.
Fields
sep: &'a str
inner: RefCell<Option<I>>
Format uses interior mutability because Display::fmt takes &self.
