Struct CudaEGraphDeviceKernelView 

pub struct CudaEGraphDeviceKernelView { /* private fields */ }

Checked kernel-facing pointer view of a CUDA-resident e-graph image.

Implementations

impl CudaEGraphDeviceKernelView

pub fn from_checked_parts( base_ptr: u64, byte_len: usize, layout: CudaEGraphDeviceByteLayout, ) -> Result<Self, BackendError>

Build a kernel view from a base pointer, byte length, and byte layout.

Errors

Returns BackendError if any layout span points outside the image or if pointer arithmetic overflows.

pub const fn base_ptr(&self) -> u64

Base device pointer of the packed e-graph image.

pub const fn byte_len(&self) -> usize

Total byte length of the resident image.

pub const fn row_count(&self) -> usize

Number of e-graph rows.

pub const fn child_count(&self) -> usize

Number of child e-class references.

pub const fn eclass_group_count(&self) -> usize

Number of grouped e-class row spans.

pub const fn row_eclass_ids_ptr(&self) -> u64

Device pointer to the row e-class id column.

pub const fn row_language_op_ids_ptr(&self) -> u64

Device pointer to the row language-op id column.

pub const fn row_children_offsets_ptr(&self) -> u64

Device pointer to the row child-offset column.

pub const fn row_children_lens_ptr(&self) -> u64

Device pointer to the row child-length column.

pub const fn row_signatures_ptr(&self) -> u64

Device pointer to the row structural-signature column.

pub const fn children_ptr(&self) -> u64

Device pointer to the flat child e-class column.

pub const fn group_eclass_ids_ptr(&self) -> u64

Device pointer to sorted grouped e-class ids.

pub const fn group_offsets_ptr(&self) -> u64

Device pointer to group prefix offsets.

pub const fn group_rows_ptr(&self) -> u64

Device pointer to row indices grouped by e-class.

Trait Implementations

impl Clone for CudaEGraphDeviceKernelView

fn clone(&self) -> CudaEGraphDeviceKernelView

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for CudaEGraphDeviceKernelView

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

Formats the value using the given formatter.

impl PartialEq for CudaEGraphDeviceKernelView

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