Struct ActionInfo 

pub struct ActionInfo<'a> {
    pub name: &'a str,
    pub type_name: &'a str,
    pub type_hash: &'a str,
    pub domain_id: u32,
}

Action information for action client/server

Actions in ROS 2 use 5 communication channels:

• send_goal service: <action_name>/_action/send_goal
• cancel_goal service: <action_name>/_action/cancel_goal
• get_result service: <action_name>/_action/get_result
• feedback topic: <action_name>/_action/feedback
• status topic: <action_name>/_action/status

Fields

name: &'a str

Action name (e.g., “/fibonacci”)

type_name: &'a str

ROS action type name (e.g., “example_interfaces::action::dds_::Fibonacci_”)

type_hash: &'a str

Type hash for compatibility checking

domain_id: u32

Domain ID (default: 0)
