Struct EqEvalLayers 

pub struct EqEvalLayers<F> {
    pub layers: Vec<Arc<DeviceBuffer<F>>>,
}

Same as EqEvalSegments but keeping segment tree with buffers separated by layer to allow dropping layers.

Fields

layers: Vec<Arc<DeviceBuffer<F>>>

Layers are reference counted so the length-1 seed layer can be shared across trees.

Implementations

impl<F> EqEvalLayers<F>

pub fn get_ptr(&self, n: usize) -> *const F

Returns start pointer for buffer of length 2^n corresponding to evaluations of eq(x[..n], -) on H_n.

impl EqEvalLayers<EF>

pub fn new_rev<'a>( n: usize, x: impl IntoIterator<Item = &'a EF>, device_ctx: &GpuDeviceCtx, ) -> Result<Self, KernelError>

Creates a new EqEvalLayers instance with layers.len() = x.len() + 1.

Inserts x_i from the front for each layer.

pub fn new<'a>( n: usize, x: impl IntoIterator<Item = &'a EF>, device_ctx: &GpuDeviceCtx, ) -> Result<Self, KernelError>

Creates a new EqEvalLayers instance with layers.len() = x.len() + 1.

Inserts x_i from the back for each layer. This matches behavior of EqEvalSegments::new.
