Struct LivelinessChangedStatus 

pub struct LivelinessChangedStatus {
    pub alive_count: i32,
    pub not_alive_count: i32,
    pub alive_count_change: i32,
    pub not_alive_count_change: i32,
    pub last_publication_handle: InstanceHandle,
}

LIVELINESS_CHANGED_STATUS — Spec §2.2.4.1 + §2.2.2.5.6.

Reader-Seite: “Reports the status of the liveliness of one or more DataWriter objects that are matched with the DataReader.”

Anders als die Plain-Counter-Statuses dürfen *_count_change hier negativ werden, wenn z.B. ein als “alive” deklarierter Writer jetzt als “not_alive” zählt (übersprungen von alive_count zu not_alive_count).

Fields

alive_count: i32

Number of currently-alive matched writers.

not_alive_count: i32

Number of currently-not-alive matched writers.

alive_count_change: i32

Change in alive_count since the last read.

not_alive_count_change: i32

Change in not_alive_count since the last read.

last_publication_handle: InstanceHandle

Handle of the last writer that triggered the change.

impl PartialEq for LivelinessChangedStatus

fn eq(&self, other: &LivelinessChangedStatus) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool
