Struct GpuAnimationBatch 

pub struct GpuAnimationBatch { /* private fields */ }

Batch of Tween<f32> values evaluated together.

The public API is intentionally small: push tweens, tick the batch, then read the current values. The CPU fallback preserves exact Tween<f32> behavior, including delays, looping, and advanced/custom easing.

Implementations

impl GpuAnimationBatch

pub fn new_cpu() -> Self

Create a CPU-only batch.

pub fn new(device: Device, queue: Queue) -> Result<Self, GpuBatchError>

Create a batch from an existing wgpu device and queue.

If an unsupported easing is pushed later, backend reports GpuBackend::Cpu and ticks continue through the exact CPU fallback path.

pub fn try_new_auto() -> Result<Self, GpuBatchError>

Try to create a GPU-backed batch using the default wgpu adapter.

pub fn new_auto() -> Self

Create a GPU-backed batch when possible, otherwise return CPU fallback.

This function never panics because GPU availability is environmental.

pub fn push(&mut self, tween: Tween<f32>) -> usize

Push a tween and return its batch index.

pub fn tick(&mut self, dt: f32)

Advance every tween by dt seconds and refresh the output buffer.

pub fn read_back(&self) -> &[f32]

Current output values, in insertion order.

pub fn backend(&self) -> GpuBackend

Currently active backend.

pub fn len(&self) -> usize

Number of tweens in the batch.

pub fn is_empty(&self) -> bool

true when the batch contains no tweens.

pub fn clear(&mut self)

Remove all tweens and output values.

pub fn shader_source() -> &'static str

WGSL shader source used by the GPU backend.

Trait Implementations
