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 roslibrust_codegen_macro::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 roslibrust_codegen_macro::find_and_generate_ros_messages;

find_and_generate_ros_messages!("/path/to/my/msg/package", "/opt/ros/noetic");
