Comparing the programming languages ​​Rust and V, if V is more beneficial, it cannot be ignored.

V language and Rust

20/03/24 11:58

On June 22, 2019, the V language was released as open source.
So far, I've been investigating various ways to develop WEB database applications with Rust, but when V language has more advantages, it cannot be ignored.
You may also need to consider switching to V language.
So, once I believed what the official V language website said, I tried to sort out the features compared to Rust.

▼ V language official website
https://vlang.io

▼ Comparison explanation with other languages ​​on the V language official website
https://vlang.io/compare


I have not actually used V language yet, but based on the above Then, it may be as follows.

	V	Rust	remarks
Executable file performance	〇	〇	It is said that it is as fast as C on the V official website, but it seems that there are cases where it is slow at the moment. I think Rust is stable and fast.
Executable files are combined into one	〇	〇	When compiled, they all seem to be one file with the smallest possible size.
Cross-compile	〇	〇	All of them can easily generate executable files natively compatible with Windows, Linux, macOS, Android, and iOS. (V language Android / iOS will be supported in the future) In particular, V is in the policy of supporting GUI toolkits on each OS as standard. Rust's GUI library is left to each manufacturer.
Compile time	〇	△	V also sells the speed of compilation. Certainly Rust isn't that fast.
Ease of learning	〇	△	Syntactically, V seems to be aware of Go's brevity. Rust still has to be written with variable ownership and lifetime in mind, and I'm having a hard time compiling ...
No garbage collection	〇	〇	Neither can set NULL for a variable. It seems that you are conscious of ensuring memory safety. Rust needs to be aware of variable ownership and lifetime for this feature, but I think it's amazing that V can achieve a garbage collection-free feature without that need. To do.
Type inference function	〇	〇	Neither requires a type declaration.
Ease of installing the library	〇	〇	Both are provided with a package manager and are easy to import.
Is there a powerful web framework?	△	〇	There is "vweb" in V, but I think it is still insufficient in terms of functionality. In Rust, it can be realized by "actix-web" and so on.
Is database connection easy?	〇	〇	"Sqlite" "Postgres" "MySQL" seems to be easily realized by introducing a library.
Is there an OR mapper?	〇	〇	V seems to come with the standard library. (I'm doing my best!) In Rust, you can do it with "diesel" .
Is there a form generation library?	??	△	V has not been investigated. I think the most sophisticated form library available in open source is Java's "JasperReport" , but I don't think there is a comparable library in Rust.
Language maker support	△	〇	Rust is well supported by Firefox maker Mozilla. V seems to have only one sponsor on the official website at the moment.
Editor support	△	△	Both seem to have basic plugins in Visual Studio Code. It seems that V also has a "Vid editor" .
Macro support	×	〇	It seems that macros cannot be used in V because it is complicated. Since V itself is simple, I think that there is no problem with that policy.
Available for free for commercial use	〇	〇

So, if I believe only the description on the website, I feel that V language has a longer day than Rust except for the support of the manufacturer.
(Manufacturer support is the most important matter in language selection)
However, until the version of V language itself becomes 1.0, it seems that many destructive changes will be made.
(Now it's 0.1.24, next is 0.2)

I personally make small apps that can develop apps using DB on the WEB without a program.
I'm developing the server side with Rust, but I think that the day will come when I have to use V language.
