break

The break statement is used to exit a loop early. It can be used with repeat, while, and for loops, as well as on and with blocks.

let x = 0
while true {
    Transmission { %(x) }
    x += 1
    if x == 5 {
        break
    }
}
// Outputs 0, 1, 2, 3, 4

Returning Values

Pass an expression to break to specify the resulting value of the loop expression.

let a = loop {
    if Tick > 10s {
        break 99
    }
    await Tick
}
// a is now `99`

Returning Multiple Values

You can pass multiple values to break to return multiple values:

let x, y, z = loop {
    if Tick > 10s {
        break 1, 2, 3
    }
    await Tick
}
// x is 1, y is 2, z is 3
