How do I check that a switch block is exhaustive in TypeScript?

Question

I have some code:

enum Color {
    Red,
    Green,
    Blue
}

function getColorName(c: Color): string {
    switch(c) {
        case Color.Red:

typescript-eslint has "exhaustiveness checking in switch with union type" rule:
