Function tokio_buf::util::iter

pub fn iter<I>(i: I) -> Iter<I::IntoIter> where
    I: IntoIterator,
    I::Item: Buf, 

Converts an Iterator into a BufStream which is always ready to yield the next value.

Iterators in Rust don't express the ability to block, so this adapter simply always calls iter.next() and returns that.
