Function extract_non_ros_args

pub fn extract_non_ros_args(
    args: impl IntoIterator<Item = String>,
) -> Result<Vec<String>, RclrsError>

Extract non-ROS arguments from program’s input arguments.

args is expected to be the input arguments of the program (e.g. std::env::args()), which are expected to contain at least one element - the executable name.

ROS arguments are arguments between --ros-args and --, with the final -- being optional. Everything else is considered as non-ROS arguments and will be left unparsed by Context::new() etc. Extracted non-ROS arguments are returned in the order that they appear by this function.

Example

let input_args = [
    "arg1", "--ros-args", "some", "args", "--", "arg2"
].map(|x| x.to_string());
let non_ros_args = rclrs::extract_non_ros_args(input_args)?;
assert_eq!(non_ros_args.len(), 2);
assert_eq!(non_ros_args[0], "arg1");
assert_eq!(non_ros_args[1], "arg2");
