Struct CpuLinkRegistry 

pub struct CpuLinkRegistry;

The built-in CPU backend’s LinkRegistry — resolves a contract’s entry_point symbols against CPU_BINARY_ENTRY_POINTS, CPU_AFFINE_CLAMP_POWI_ENTRY_POINTS, CPU_UNARY_ENTRY_POINTS, CPU_COMPARE_ENTRY_POINTS, CPU_WHERE_ENTRY_POINTS, CPU_REDUCE_ENTRY_POINTS, CPU_REDUCE_TO_ENTRY_POINTS, CPU_NORM_ENTRY_POINTS, CPU_NORM_BACKWARD_ENTRY_POINTS, CPU_ROPE_ENTRY_POINTS, CPU_SSM_ENTRY_POINTS, CPU_CONV_ENTRY_POINTS, CPU_PADDING_ENTRY_POINTS, CPU_SHAPE_OPS_ENTRY_POINTS, CPU_INDEXING_ENTRY_POINTS, CPU_MATMUL_ENTRY_POINTS, CPU_ATTENTION_ENTRY_POINTS, CPU_INPLACE_ENTRY_POINTS, and CPU_CAST_ENTRY_POINTS. Unresolved → None, which the importer turns into a typed UnknownEntryPoint error (never a panic, never a fabricated pointer).

Trait Implementations

impl LinkRegistry for CpuLinkRegistry

fn resolve_primitive(&self, symbol: &str) -> Option<KernelRef>

Resolve a primitive (op_kind) kernel’s entry point.

fn resolve_fused(&self, symbol: &str) -> Option<KernelRef>

Resolve a fused (fused_op) kernel’s entry point.

fn resolve_cost_fn(&self, _name: &str) -> Option<CostFn>

Resolve a contract’s cost.cost_fn NAME into a concrete CostFn pointer — the cost-model analogue of Self::resolve_primitive (§4.4 cost-fn trampoline, Task-F). A provider that pins real cost fns exports its own &'static [(&str, CostFn)] table and overrides this over it (exactly as it exports its entry_point table); the built-in default is None (no cost-fn table), so every existing LinkRegistry impl and test stub compiles unchanged and a section that names no cost fn is unaffected. The importer never fabricates a pointer: an unresolved name is a typed FkcError::UnknownCostFn, never a silent unknown_cost fallback (P9 — the resolved cost model is a real registered fn, not a serialized pointer).
