The OPC UA Types module contains data types and enumerations for OPC UA.

deregister_runtime_component
See register_runtime_component
register_runtime_component
This macro is for debugging purposes - code register a running component (e.g. tokio task) when it starts and calls the corresponding deregister macro when it finishes. This enables the code to print out a list of components in existence at any time to ensure they were properly cleaned up.
runtime_components
Returns a vector of all currently existing runtime components as a vector of strings.
supported_message_as
trace_lock
Tracing macro for obtaining a lock on a Mutex. Sometimes deadlocks can happen in code, and if they do, this macro is useful for finding out where they happened.
trace_read_lock
Tracing macro for obtaining a read lock on a RwLock.
trace_write_lock
Tracing macro for obtaining a write lock on a RwLock.
