I don't know Rust, so your program is a bit of an introduction.

I also started not far away a go, I come from C and GO.

With that in mind, I wonder if this wouldn't be a little bit
better:

Not a problem is why I link it to this newsgroup ;)

Would that work?  If so, it would let you change the entry format
in "entry" in only one place, if you decide to do so.

This indeed will save some lines of code, but from my security best
habits in coding I always try to limit the amount of stdin that can be
added, so if I split variables I have a better way to handle each value
and avoid the user input to do things it was not supposed to.

(Also, was intrigued by how "let" seems to work, if I understand it correctly.
Will have to take a look at Rust!)

Yeah takes time to get used to the new wording and such but is nice when
you pick it up.

Finally, I've long been disappointed that git doesn't preserve
timestamps on files.  Does anyone know of any discussion about
why that is, and perhaps changing git to have that capability?

No problem you can always ask your news server admin to add it.
and I think it did came in to alt.comp.lang.rust I am reading it there.
