Throwing error over tvm::ffi::StructuralWalkExpected.

See tvm::ffi::StructuralWalkExpected for callback semantics and traversal behavior.

Template Parameters:

  • order – Whether to invoke the callback before or after visiting children.

  • Callbacks – Callback types.

Parameters:

  • root – The root value to visit.

  • callbacks – Callbacks invoked for matching nodes. Each callback may take either (value) or (value, def_region_kind) and should return Expected<WalkResult>.

Throws:

Error – if traversal or a callback returned an error.

Returns:

std::nullopt if traversal completed, or the interrupt returned by a callback.
