pub fn join<I, S>(iter: I, sep: S) -> Join<I::IntoIter, S>where
I: IntoIterator,
I::IntoIter: Clone,Expand description
Concatenates Iterator items with a separator between each.
This may be used as a non-allocating alternative to
[T]::join()
or itertools::join().
If Clone for the Iterator is too expensive, consider using
join_once().
Examples
let value = fmty::join(["hola", "mundo"], " ");
assert_eq!(value.to_string(), "hola mundo");
