Enum TensorMemory 

pub enum TensorMemory {
    Dma,
    Shm,
    Mem,
    Pbo,
}

Variants

Dma

Platform-native zero-copy GPU buffer.

On Linux this is a DMA-BUF (DmaTensor in crates/tensor/src/dma.rs) allocated via the DRM/dma-heap subsystem. On macOS this is an IOSurface (IoSurfaceTensor in crates/tensor/src/iosurface.rs). Both fit into the same TensorStorage::Dma slot at the trait level — the public C API discriminant (HalTensorMemory::Dma=1) works on both platforms with no ABI break.

Allows hardware-accelerated paths (OpenGL backend on Linux via EGL_EXT_image_dma_buf_import; macOS via EGL_ANGLE_iosurface_client_buffer). CPU access via map() incurs cache-coherency overhead on Linux DMA-BUF and is similar in cost on IOSurface; SHM/Mem are cheaper for CPU-only workloads.

Shm

POSIX Shared Memory allocation. Suitable for inter-process communication, but not suitable for hardware acceleration.

Mem

Regular system memory allocation

Pbo

OpenGL Pixel Buffer Object memory. Created by ImageProcessor when DMA-buf is unavailable but OpenGL is present.

Trait Implementations

impl Clone for TensorMemory

fn clone(&self) -> TensorMemory

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for TensorMemory

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

Formats the value using the given formatter.

impl From<TensorMemory> for String

fn from(memory: TensorMemory) -> Self

Converts to this type from the input type.

impl PartialEq for TensorMemory

fn eq(&self, other: &TensorMemory) -> 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.

impl TryFrom<&str> for TensorMemory

type Error = Error

The type returned in the event of a conversion error.

fn try_from(s: &str) -> Result<Self>

Performs the conversion.
