Struct KernelInstance 

pub struct KernelInstance {
    pub name: String,
    pub source: String,
    pub runtime_op: Arc<dyn RuntimeOp>,
    pub backward: Option<KernelInstanceBackward>,
}

A concrete, dtype-resolved kernel produced by a #[kernel(dtypes = [...])] dispatcher (or a kernel_group!).

It is deliberately crate-agnostic: it carries only the pieces needed to assemble a compilable unit (teeny-kernels’ KernelExecutable), while living in teeny-core so the #[kernel] macro can reference it from any consuming crate without a dependency on teeny-kernels.

Fields

name: String

Forward kernel name (used to derive the entry-point symbol).

source: String

Combined forward kernel source (kernel_source + entry_point).

runtime_op: Arc<dyn RuntimeOp>

Runtime dispatch object for arg-packing and launch config.

backward: Option<KernelInstanceBackward>

Backward kernel, present only when the kernel declares one.
