Struct itertools::format::Format

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

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.
