Function Documentation#

json::Value tvm::ffi::ToJSONGraph(const Any &value, const Any &metadata = Any(nullptr))#

Serialize ffi::Any to a JSON that stores the object graph.

The JSON graph structure is stored as follows:

{
  "root_index": <int>,        // Index of root node in nodes array
  "nodes": [<node>, ...],     // Array of serialized nodes
  "metadata": <object>        // Optional metadata
}

Each node has the format: {"type": "<type_key>", "data": <type_data>} For object types and strings, the data may contain indices to other nodes. For object fields whose static type is known as a primitive type, it is stored directly, otherwise, it is stored as a reference to the nodes array by an index.

This function preserves the type and multiple references to the same object, which is useful for debugging and serialization.

Parameters:

  • value – The ffi::Any value to serialize.

  • metadata – Extra metadata attached to “metadata” field of the JSON object.

Returns:

The serialized JSON value.
