first of all i learned smth like there is no default mutable variable in Rust.
You must write smth like \"let mut x = 5;\"
and the second one is bro, rust have dynamic arrays...damn bro its python or what bro what is dynamic arrays bro i ll cry :sob: (yk)
So its the primitve types in Rust programming languages;

// the primitive types in Rust programming language

fn main() {\n// integer\nlet sum = 5 + 10;\nprintln!(\"{}\", sum);\n\n//char\nlet heart_eyed_cat = '😻';\nprintln!(\"{}\", heart_eyed_cat);\n\n//bools\nlet t = true;\nlet f: bool = false;\nprintln!(\"{}\\n{}\", t, f);\n\n//tuples\nlet tup: (u32, u64, char) = (500, 600, 's');\nprintln!(\"{:?}\", tup);\n//acces to element of a tuple\nlet tup1 = tup.1;\nprintln!(\"{}\", tup1);\n//bacarrame\n\n//arrays and yes Rust have dynamic arrays and its so basic\n\nlet _xs = [1, 2, 3, 4, 5];\n/*You write an array’s type using\n * square brackets with the type of each element,\n * a semicolon, and then the number of\n * elements in the array, like so:*/\n\nlet smthn : [i32; 5] = [1, 2 , 3, 4, 5];\nprintln!(\"{:?}\", smthn);\nprintln!(\"{:?}\", _xs);\n}
