The first two is the same article, but they point out that certain structures can be very hard to write in rust, with linked lists being a famous example. The point stands, but I would say the tradeoff is worth it (the author also mentions at the end that they still think rust is great).

The third link is absolutely nuts. Why would you want to initialize a struct like that in Rust? It's like saying a functional programming language is hard because you can't do goto. The author sets themselves a challenge to do something that absolutely goes against how rust works, and then complains how hard it is.

If you want to do it to interface with non-rust code, writing a C-style string to some memory is easier.
