pub struct Format<'a, I> {
    sep: &'a str,
    inner: RefCell<Option<I>>,
}
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 strinner: RefCell<Option<I>>

Format uses interior mutability because Display::fmt takes &self.
