error: use of unstable library feature 'iter_arith'

When running cargo build, I get the following:

   Compiling osm4routing v0.1.0 (file:///home/juliencoupey/Documents/repos/forks/osm4routing2)
src/osm4routing/models.rs:50:79: 50:84 error: use of unstable library feature 'iter_arith': bounds recently changed (see issue #27739)
src/osm4routing/models.rs:50         self.geometry.windows(2).map(|coords| distance(coords[0], coords[1])).sum()
                                                                                                           ^~~~~

The linked issue and the way it has been closed seems to point out the need to have a recent rust version. I've currently only installed the somewhat outdated 1.7.0 from the ubuntu repos.

Is there a simple workaround or do I need to install a recent rust? In which case it may be worth adding the required version in readme. ;-)

I suppose that indeed a newer version should work. Could you try to install a newer version?
With https://www.rustup.rs/ it’s quite easy. It might also fix the other issue you had.

(Thanks for reporting the problems)

Currently running through rustup.sh before piping to sh...

Thanks for the answer, solved by using version 1.13.0.
