Trait Haptics 

pub trait Haptics: Send + Sync {
    // Required method
    fn perform(&self, feedback: HapticFeedback);

    // Provided methods
    fn vibrate(&self, duration_ms: u32, amplitude: u8) { ... }
    fn play_pattern(&self, pattern: &HapticPattern) { ... }
    fn perform_effect(&self, effect: HapticEffect) { ... }
    fn cancel(&self) { ... }
    fn has_amplitude_control(&self) -> bool { ... }
}

Re-export framework services (HTTP, URI, etc.) from the dedicated services crate. Performs haptic feedback. Installed by the platform backend; the default is a no-op.

Only perform has to be implemented. Every other method falls back to it, so extending this trait cannot break an existing backend.

Required Methods

fn perform(&self, feedback: HapticFeedback)

Plays a semantic feedback event.

Provided Methods

fn vibrate(&self, duration_ms: u32, amplitude: u8)

Vibrates once for duration_ms at amplitude (1 to 255; 0 means the device default strength).

Maps to VibrationEffect.createOneShot(long, int) on Android. The defaulted body picks the closest HapticFeedback constant.

fn play_pattern(&self, pattern: &HapticPattern)

Plays a waveform pattern.

Maps to VibrationEffect.createWaveform(long[], int[], int) on Android. The defaulted body plays HapticPattern::closest_feedback once.

fn perform_effect(&self, effect: HapticEffect)

Plays a system-defined primitive.

Maps to VibrationEffect.createPredefined(int) on Android. The defaulted body plays HapticEffect::closest_feedback.

fn cancel(&self)

Stops any vibration in progress, including a repeating waveform. Backends with no way to cancel leave this as a no-op.

fn has_amplitude_control(&self) -> bool

Whether the device reproduces amplitudes rather than treating every non-zero level as full strength.

Dyn Compatibility

This trait is dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety".
