roslibrust_codegen_macro
This crate defines the proc-macro for generating ROS message types. It invokes APIs from the roslibrust_codegen
crate.
Warning
This macro cannot detect if the message files it generates from have changed. If you are creating a crate which just contains your message definitions and won't be recompiled otherwise, you'll likely want to use roslibrust_codegen
with a build.rs
script.
Usage
If you're generating messages in an environment with ROS installed, no arguments need to be passed.
use find_and_generate_ros_messages;
find_and_generate_ros_messages!;
If you're generating without ROS installed or your environment can't depend on the ROS_PACKAGE_PATH
variable, you can specify additional paths to search:
use find_and_generate_ros_messages;
find_and_generate_ros_messages!;
