Function from_iter 

pub fn from_iter<I: IntoIterator>(it: I) -> FromIter<I::IntoIter> 

“Lifts” / converts an [Into]Iterator into an impl LendingIterator

• This is a free function version of the .into_lending_iter() method provided by the eponymous extension trait.

  That is, feel free to check out that extension method, since in practice it’s even more ergonomic to use.

• See the .into_iter() method on LendingIterator for the reverse operation.
