Function itertools::merge

pub fn merge<I, J>(
    i: I,
    j: J
) -> Merge<<I as IntoIterator>::IntoIter, <J as IntoIterator>::IntoIter>where
    I: IntoIterator,
    J: IntoIterator<Item = I::Item>,
    I::Item: PartialOrd,

Create an iterator that merges elements in i and j.

IntoIterator enabled version of Itertools::merge.
