Hi all,
I'm a newcomer to Rust. One of the things that I find confusing is
the use of {} in formatted strings. In all other languages I've ever
used, it's always %. So instead of writing "%d", you write "{:d}" in
Rust. Why is this so? What benefits do we get?
Thanks,
Derek

In addition to what Daniel said, being statically typed mean you can
normally just write `{}` and let the std::fmt::Default implementation
handle everything (for the primitive types it's the same as the {:d},
{:f}, {:s} etc).
