Struct ActionClientCallback 

pub struct ActionClientCallback<A: RosAction, const GOAL_BUF: usize = { crate::config::DEFAULT_RX_BUF_SIZE }, const RESULT_BUF: usize = { crate::config::DEFAULT_RX_BUF_SIZE }, const FEEDBACK_BUF: usize = { crate::config::DEFAULT_RX_BUF_SIZE }> { /* private fields */ }

Send handle for a callback-based typed action client.

Returned by create_action_client_with_callbacks: goal-response, feedback, and result are delivered to the registered closures at spin_once (no Promise poll). This handle only sends — it holds a *mut to the arena entry’s ActionClientCore (offset 0, pinned in the executor arena, like a guard-condition flag).

Safety / lifetime

Valid only while the owning executor lives.

Implementations

impl<A: RosAction, const GOAL_BUF: usize, const RESULT_BUF: usize, const FEEDBACK_BUF: usize> ActionClientCallback<A, GOAL_BUF, RESULT_BUF, FEEDBACK_BUF>

pub fn send_goal(&mut self, goal: &A::Goal) -> Result<GoalId, NodeError>

Send a typed goal. Returns its GoalId; acceptance arrives via the registered goal-response callback.

pub fn get_result(&mut self, goal_id: &GoalId) -> Result<(), NodeError>

Request the result for goal_id; the result arrives via the registered result callback.
