EventUser

epics_base_rs::server::event_queue

Struct EventUser 

Source 
pub struct EventUser { /* private fields */ }
Expand description

C event_user (dbEvent.c:84-105) — one per CA circuit. Owns the EVENTS_OFF flag and the chain of queues subscriptions attach to.

Implementations§

Source§

impl EventUser

Source

pub fn new() -> Self

C db_init_events.

Source

pub fn flow_ctrl_on(&self)

C db_event_flow_ctrl_mode_on — EVENTS_OFF. Posts now replace each monitor’s last queued entry in place, and a reader suspends once its queue holds no duplicates.

Source

pub fn flow_ctrl_off(&self)

C db_event_flow_ctrl_mode_off — EVENTS_ON. Releases every suspended reader on this circuit; C posts ppendsem for the same reason.

Source

pub fn is_flow_ctrl_on(&self) -> bool
