Struct EqEvalSegments

Source

pub struct EqEvalSegments<F> { /* private fields */ }

Expand description

For a fixed x in F^max_n, stores the evaluations of eq_n(x[..n], -) on hypercube H_n for n = 0..=max_n. The evaluations are stored contiguously in a single buffer of length `2^(max_n

1). We define eq_0 = 1` always.

Implementations§

Source §

impl<F> EqEvalSegments<F>

Source

pub fn buffer(&self) -> &DeviceBuffer<F>

Index 0 is unused and initialized to zero. Index 1 stores the length-1 eq_0 = 1 layer.

Source §

impl<F> EqEvalSegments<F>

Source

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.

Source

pub unsafe fn from_raw_parts(buffer: DeviceBuffer<F>, max_n: usize) -> Self

§Safety

Caller must ensure that buffer has length 2^{max_n + 1} and is properly initialized.

Source §

impl EqEvalSegments<EF>

Source

pub fn new(x: &[EF], device_ctx: &GpuDeviceCtx) -> Result<Self, KernelError>

Creates a new EqEvalSegments instance with max_n = x.len().
