Using Vec::new () Method: let v : Vec = Vec::new (); Here v is the initialized vector that will contain the 64-bit integer datatype. It is initialized with help of the Vec::new () method. Rust fn main () { let v : Vec = Vec::new (); WebA fixed-size array, denoted [T; N], for the element type, T, and the non-negative compile-time constant size, N. There are two syntactic forms for creating an array: A list with each element, i.e., [x, y, z]. A repeat expression [x; N], which produces an array with Ncopies of x. The type of xmust be Copy.
