pub struct Format<'a, I> {
sep: &'a str,
inner: Cell<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 str
§inner: Cell<Option<I>>
Format
uses interior mutability because Display::fmt
takes &self
.
