Enum GpuMemoryStrategy 

pub enum GpuMemoryStrategy {
    FullVolume,
    Chunked {
        chunk_count: usize,
        slices_per_chunk: usize,
    },
    SlidingWindow {
        window_size: usize,
    },
    OnDemand,
}

GPU memory strategy for volume storage

Variants

FullVolume

Entire volume in GPU memory (fastest)

Chunked

Volume split into multiple chunks along Z-axis (for volumes > 2GB) Each chunk fits within WebGPU buffer limits

Fields

chunk_count: usize

Number of chunks

slices_per_chunk: usize

Slices per chunk (except possibly last chunk)

SlidingWindow

Sliding window of slices (for large volumes, MPR only)

Fields

window_size: usize

OnDemand

Transfer each slice on demand (slowest but always works)

Implementations

impl GpuMemoryStrategy

pub fn determine( volume_memory_mb: usize, available_vram_mb: Option<usize>, dimensions: Option<[usize; 3]>, ) -> Self

Determine best strategy based on volume size, VRAM, and WebGPU buffer limits

pub fn determine_simple( volume_memory_mb: usize, available_vram_mb: Option<usize>, ) -> Self

Legacy determine without dimensions (for backward compatibility)

Trait Implementations

impl Clone for GpuMemoryStrategy

fn clone(&self) -> GpuMemoryStrategy

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for GpuMemoryStrategy

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl PartialEq for GpuMemoryStrategy

fn eq(&self, other: &GpuMemoryStrategy) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
