auto sequant::make_evaluator(BatchPolicy const &policy, F yielder, ScopeGuardFactory make_scope_guard = {})

Builds a batched custom evaluator (see make_batched_custom_evaluator) from a policy object, lifting the policy’s canonical Tensor-based volatile-leaf predicate to the EvalNode predicate the batched evaluator expects.

Exactly equivalent to calling make_batched_custom_evaluator with:

  • target_batch_size = policy.batch_target_size

  • accept = policy.is_batchable_index

  • make_scope_guard = make_scope_guard (forwarded)

  • is_volatile = EvalNode lift of policy.is_volatile_leaf: n.leaf() && n->is_tensor() && policy.is_volatile_leaf(n->as_tensor()) (when policy.is_volatile_leaf is empty, no node is volatile)

Parameters:

  • policy – BatchPolicy carrying the three batchability predicates.

  • yielder – The leaf evaluator (captured and forwarded).

  • make_scope_guard – Optional scope-guard factory (same semantics as in make_batched_custom_evaluator; defaults to make_no_scope_guard).
