pub type NemoRelayNativeAsyncNextResultCb = unsafe extern "C" fn(user_data: *mut c_void, value_json: *const NemoRelayNativeString, error: *const NemoRelayNativeString);Expand description
Receives one completion from a unary execution-continuation invocation.
Exactly one of value_json and error is non-null. The callback owns its
user_data and is invoked exactly once after a successful
async_next_invoke_result call, including when the owning interceptor
settles and cancels unfinished downstream work.
