Struct ExecutionNode 

pub struct ExecutionNode {
    pub id: u64,
    pub device: DeviceSpec,
    pub inputs: Vec<BufferId>,
    pub outputs: Vec<BufferId>,
    pub predecessors: Vec<u64>,
    pub is_transfer: bool,
    pub buffer_access: Option<KernelBufferAccess>,
}

A node in the execution graph representing a kernel or transfer operation.

Fields

id: u64

Unique identifier for this node (typically the kernel AST ID).

device: DeviceSpec

Device this operation executes on.

inputs: Vec<BufferId>

Buffer IDs read by this operation.

outputs: Vec<BufferId>

Buffer IDs written by this operation.

predecessors: Vec<u64>

IDs of nodes that must complete before this one (dependencies).

is_transfer: bool

Whether this is a data transfer (COPY) or a computational kernel.

buffer_access: Option<KernelBufferAccess>

Buffer access information for parallel execution. Contains the full buffer list and output indices for dependency tracking.
