The array type is [T; length]. Array initializationIn the first example, we initialize arrays in Rust. main.rs fn main() { let vals: [i32; 5] = [1, 2, 3, 4, 5]; println!("{:?}", vals); let words = ["soup", "falcon", "water", "tree"]; println!("{:?}", words)...
Array Declaration: let arr: [i32; 3]: Declares a variable named arr of type array ([i32; 3]). i32 specifies the type of elements in the array (32-bit signed integers). 3 specifies the length of the array. Array Initialization: = [1, 2, 3];: Initializes the array with three ele...

A good compromise could be to only check if a const value is used to initialize an array if the code is inside a function body. That would limit the scope of the search. As this is theoretically working as intended, I'll mark this as a possible enhancement of the lint 🙃 @rustbot...

There's a shorthand to initialize Arrays with a certain size that does not require you to type in 100 items (but you certainly can if you want!). For example, you can do: let array = ["Are we there yet?"; 10]; Bonus: what are some other things you could have that would return...
