Function dora_send_output 

#[unsafe(no_mangle)]
pub unsafe extern "C" fn dora_send_output(
    context: *mut c_void,
    id_ptr: *const u8,
    id_len: usize,
    data_ptr: *const u8,
    data_len: usize,
) -> isize

Sends the given output to subscribed dora nodes/operators.

The id_ptr and id_len fields must be the start pointer and length of an UTF8-encoded string. The ID string must correspond to one of the node’s outputs specified in the dataflow YAML file.

The data_ptr and data_len fields must be the start pointer and length a byte array. The dora API sends this data as-is, without any processing.

Safety

• The id_ptr and id_len fields must be the start pointer and length of an UTF8-encoded string.
• The data_ptr and data_len fields must be the start pointer and length a byte array.
