CompletedResultEntry

Struct CompletedResultEntry 

Source
pub struct CompletedResultEntry {
    pub goal_id: GoalId,
    pub status: GoalStatus,
    pub offset: usize,
    pub len: usize,
    pub delivered: bool,
}
Expand description

Completed goal result metadata — indexes into the result slab.

Entries are kept in completion order, which is also increasing offset order: results are appended at result_slab_used and the slab is compacted in place whenever an entry is reclaimed. Every reclamation path preserves that ordering (heapless::Vec::remove / retain, never swap_remove) because ActionServerCore::compact_result_slab moves survivors down and would clobber a not-yet-moved entry otherwise.

Fields§

§goal_id: GoalId

Unique identifier for the completed goal.

§status: GoalStatus

Terminal status of the goal.

§offset: usize

Byte offset into the result slab.

§len: usize

Length of the serialised result in bytes.

§delivered: bool

true once a get_result reply carrying this result has been sent — either the deferred flush in ActionServerCore::complete_goal_raw or the immediate reply in ActionServerCore::try_handle_get_result_raw.

Issue 0796: this is the reclamation priority. A delivered result has served its purpose (rcl would let its result_timeout retire it), so it is evicted before any result nobody has fetched yet.
