There are no silver bullets, and if the Rust Hype Squad told you there were and all you had to do was buy their product, they were just bamboozling you to push adoption of their pet language.
Write in whichever language you like. Including Rust. Including C. Even PHP. You can write secure software if you put your mind to it.
And honestly? No! If someone can kick your door down, don't waste your money on a super-secure lock, they will just kick your door down. And if you're having your door kicked down on the regular, don't even focus on bolstering the door (they'll either start using power tools or take some other tact like smashing your windows or drilling through the floor or roof). Leave the door open if you like, but move whatever's attracting the attention of intruders somewhere more defensible. Focusing on the securing the wrong thing is also a security flaw!
