If you are hoping to get True if the result is not empty, you might want to use:

i think you are looking for this:

If you don't want to add a IsNull-function in you SQL (as Nathan_Sav suggested as a comment): There is a IsNull-function in VBA. With that, you can create a simple function that returns for example an empty string (or a 0 or whatever you prefer):

Basically, the problem at hand is that rodio::Decoder::new consumes the value which it reads from (well, actually it is already consumed by BufReader::new). So, if you have a loop or a closure that can be called multiple times, you have to come up with a fresh value each time. This what File::open does in your first code snipped.

In your second code snipped, you only create a File once, and then try to consume it multiple times, which Rust's ownership concept prevents you from doing.

Also notice, that using reference is sadly not really an option with rodio since the decoders must be 'static (see for instance the Sink::append trait bound on S).

If you think your file system is a bit slow, and you want to optimize this, then you might actually want to read the entire file up-front (which File::open doesn't do). Doing this should also provide you with a buffer (e.g. a Vec) that you can clone, and thus allows to repeatedly create fresh values that can be consumed by the Decoder. Here is an example doing this:

Please enable the quarkus-smallrye-jwt TRACE logging to see why the tokens are rejected. And indeed, as you have also found out, https protocol needs to be enabled in the native image, which can be done, as you have shown :-), by adding --enable-url-protocols=https to the native profile's properties in pom.xml.

This PR will ensure adding it manually won't be required.

Your immediate issue is that T: GarbageBin<'a, 'b> where 'a and 'b are parameters of create_bin_with_rubbish and must therefore outlive calls to that function—but the actual lifetimes passed to T::new are only internal to the function and do not therefore satisfy those bounds.

Instead of parameterising create_bin_with_rubbish with lifetimes 'a and 'b, one way to resolve this would be to use instead an HRTB (higher-ranked trait bound):

This is not possible. The reason is that converting a Unicode String to lowercase/uppercase may need to reallocate the String, as case folding within Unicode might need more/fewer characters and/or bytes to encode the folded variant.

Either you can return a Vec, where the new String holds the conversion. Or, if you are sure that your input is pure ASCII, you take use make_ascii_lowercase to do the conversion in-place; this has the downside that if proper Unicode folding requires more/less characters/bytes, no folding takes place.

Redis doesn't define structured serialization formats. It mostly store strings and integers. So you have to choose or define your format for your struct.

A popular one is JSON, as you noticed, but if you just want to (de)serialize simple pairs of (id, description), it's not very readable nor convenient.

In such a case, you can define your own format, for example the id and the description with a dash in between:

You're comparing your plain sql query string (DBConstants.GET_VEHICLE_REG_NUMBER) to the vehicleRegNumber parameter and no wonder they don't match.

What you need to compare is the result from your ps.executeQuery(); which is assigned to ResultSet rs.
