The term Rust Belt is generally attributed to Walter Mondale, who referred to this part of the country in that way when he was the Democratic presidential candidate in 1984. Attacking then-PresidentRonald Reagan, Mondale claimed that his opponent’s policies were ruining what he called the Rust...
However, Rust's traits fix one major problem (well, they fix several major problems, but one that's relevant here) with Java's interfaces. In Java, if you define an interface, then anyone writing a class can implement the interface, but you can't implement it for other people....

This can be done by making sure that there doesn't exist an equation to derive one r value from another. So this Rust implementation of ECDSA protects against this by making sure that the RNG relies on the combination of the random nonce-key, the hash over the mes...
Which is why Rust is unable to find lifetimes that match your requirements. In your second version, you make the mutable borrow independent (or, at least, not forcly equal to) from the lifetime of &mut Thing, and therefore of a. Rust can then make 'b shorter than ...
