## Methods

- `allAtOnce(): TrafficRouting // chainable` (static) — Shifts 100% of traffic in a single shift.

- `bind(scope: Construct): TrafficRoutingConfig` — Returns the traffic routing configuration.

- `timeBasedCanary(props: TimeBasedCanaryTrafficRoutingProps): TrafficRouting // chainable` (static) — Shifts a specified percentage of traffic, waits for a specified amount of time, then shifts the rest of traffic.

- `timeBasedLinear(props: TimeBasedLinearTrafficRoutingProps): TrafficRouting // chainable` (static) — Keeps shifting a specified percentage of traffic until reaching 100%, waiting for a specified amount of time in between each traffic shift.
