            Can't Convert SystemTime to Prost 0.10/Protobuf Timestamp Type
            Asked 2022-Apr-15 at 09:45

            Can somebody tell me what is happening with the types in tonic and prost? Only a month or two ago, my team had a working build that used a protobuf definition that contained a timestamp. We're compiling them with tonic_build using well known types. Something changed with the types moving from prost 0.7 to 0.10 and now I get this error.

            How to come up with a normal solution to the problem of brute force?
            Asked 2022-Mar-21 at 11:55

            I came across an interesting problem. The input is a number from 1..n, where n <= 10^9. So you need to make a prime number out of it by changing its digits. Moreover, you need to change as few digits as possible, and if there are several such options, then you need to minimize the number. For, example 10, answer is 11.

            This task passed all my tests and was accepted in the checking system. But my decision seems strange and quackish.

            I considered a few cases on small numbers, and considering that prime numbers occur quite often, I decided to iterate over one digit of the number first and replace it with any from 0..9. But this solution fell on the 5th test. After that, I decided to add a search of the second digit and then the solution passed the tests.

            It turns out that my solution works for the asymptotic len(n)^281sqrt(n). Which is good. But I absolutely cannot prove why 2 digits is enough. And suddenly there are some numbers where you need to replace 3 digits or more.

            Please help me figure out why this is true, or help me come up with some kind of normal solution.

            I think this can be explained by a few observations/factors.

            1. Most centuries (xxxx00 to xxxx99) have at least one prime.
            2. The first century without a prime is 1671800.
            3. The first millenium without a prime is 13893290219204000 (which is sufficiently greater than 10^9).

            If you combine these factors, it's easy to see why most numbers can be made prime by changing two digits (since a large number of centuries have primes). And if the century doesn't have a prime, then changing three digits is guaranteed to give a solution, since each millenium in the given range has a prime number.

            encode_to_vec is not a free function. You need to call it as one of

            • f.encode_to_vec()
            • foo::Foo::encode_to_vec(&f)
            • Message::encode_to_vec(&f)
            • ::encode_to_vec(&f)

            The first method is the most normal, but the other ones may produce useful error messages when you get confused about what's going on.

            [Edit:] Well, encode_to_vec was added in prost 0.8.0, so with 0.7.0, it won't be usable.

            Editions are separately chosen by each crate being compiled. The current revision of the ed25519 crate requires a compiler that supports the 2021 edition. (You can find this out through docs.rs's handy source view: https://docs.rs/crate/ed25519/1.4.0/source/Cargo.toml.orig)

            If you're trying to compile Rust binaries using a fixed compiler version (or an older version that might be in your distro package manager), then it's important to include a Cargo.lock file in your project/container configuration. The lock file specifies exact versions of each crate, so that your build cannot be broken by new library versions requiring newer compiler features.

            However, there's a catch: cargo install ignores the lock file by default. So, you'll also need to change your command to pass the --locked flag to cargo install.

            (You should also consider using a newer Rust compiler version, so that you don't have to use old versions of libraries that may have known bugs.)

            Rust / Prost : How do add Debug to structs & unions?
            Asked 2021-Nov-07 at 21:28

            It looks like the prost protobuf generator only adds derive(Debug) to generated enum types (and only enums not inside a pub mod block). None of the generated structs, or unions have it applied. How can I get prost to add it to everything?

            prost doesn't have an option to turn that on so you have to do it yourself.

            If you want to implement a trait for a type. You need to have either the trait or the type in your library/binary.

            Since the trait is in std and the type is in an external crate the best you can do is create a unit struct to wrap the type. Then implement Debug for that.

            It is not a good idea to compare hours with hours, minutes with minutes and second with seconds to find which HH:MM:SS combination is the fastest. There can be cases like 04:50:56 < 05:00:00, which does not evaluate well in your original compareTo() method.

            The option is #[cfg(test)] (singular), not #[cfg(tests)] (plural). This is probably not failing because it's not being compiled or run at all, since the option is never set.
