Re-exports

pub use messages::Message;

pub use messages::MessageType;

pub use messages::RequestMessage;

pub use messages::ResponseMessage;

pub use tracing;

Modules

comms

Contains all code related to sending / receiving messages from a transport and turning those messages into and out of chunks.

config

Common utilities for configuration files in both the server and client.

constants

Contains common OPC-UA constants.

debug

Contains debugging utility helper functions

handle

Utility for producing sequential message handles.

messages

RequestMessage and ResponseMessage, and utilities for working with these.

sync

Common synchronous locks. Re-exports locks from parking_lot used internally.

Macros

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.

Functions

trace_locks

Check for the environment variable OPCUA_TRACE_LOCKS. If it is set to 1 or true, then tracing will be enabled for locks. This is useful for debugging deadlocks.
