Hi Avro users,
I'm having trouble with the avro_value_set_branch function. Hoping anyone
can chime in here.
Schema for a node in a binary tree:
{
"type": "record",
"name": "node",
"fields": [
{"name": "featureIndex", "type": "int"},
{"name": "split", "type": "double"},
{"name": "value", "type": "double"},
{"name": "left", "type": ["node", "null"]},
{"name": "right", "type": ["node", "null"]}
]
}
Here's the code snippet leading up to the error.
avro_value_t node;
avro_value_t field;
avro_value_t branch;
avro_generic_value_new(valueIface, &node); //valueIface was instantiated
with the schema below
avro_value_get_by_name(&node, "left", &field, NULL);
avro_value_t leftNode = some other node that I'd like to copy into the
"left" field of the "node" variable
avro_value_set_branch(&field, 0, &branch); //no error here
avro_value_copy(&branch, &leftNode); //"Union has no selected branch" error
is thrown here
But it works if I do:
avro_value_set_branch(&field, 1, &branch);
avro_value_set_null(&branch);
The only other example I could find is this

Thanks
in advance for looking.
