“fn” was just one example. There’s also other abbreviations like “pub”, “impl”, “extern”, “mut”, “ref”, “bool”, “u64” And it’s true that some of these keywords are only relevant in Rust, however other langues have their own specific keywords, and they tend to be longer. In languages like Java (which is the worst example I can think of), you see things like “private static boolean” as function definition. In c++, you have to type “unsigned long” or even “unsigned long long” to represent “u64” (depending on data model).

To be fair, in C/C++ you can include
stdint.hwhich defines type aliases such asuint64_t.
