Struct itertools::format::FormatWith

source ·

pub struct FormatWith<'a, I, F> {
    sep: &'a str,
    inner: RefCell<Option<(I, F)>>,
}

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_with() for more information.

Fields

sep: &'a strinner: RefCell<Option<(I, F)>>

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