Operators

Arithmetic

let a = 10 + 2
let b = 10 - 2
let c = 10 * 2
let d = 10 / 2
let e = 10 % 3

Comparison

let eq = 10 == 10
let ne = 10 != 20
let lt = 10 < 20
let ge = 20 >= 10

Logical

let ok = true && !false
let either = false || true

Assignment

let mut score = 0
score += 5
score -= 2
score *= 3

Type Operators

let wide: i64 = 42
let small: i32 = wide as i32

let token: (i32, bool) = (7, true)
if token[0] is i32 {
    println("ok")
}

Use as for explicit casts and is for type-pattern checks with unions/interfaces.
