Struct GuardCondition 

pub struct GuardCondition { /* private fields */ }

Implementations

impl GuardCondition

pub fn new(participant: &DomainParticipant) -> DdsResult<Self>

Create a guard condition on participant, holding it alive.

pub unsafe fn from_entity(participant: dds_entity_t) -> DdsResult<Self>

Create a guard condition from a raw participant handle.

Safety

Does not hold the participant alive. Prefer GuardCondition::new.

pub fn set_triggered(&self, triggered: bool) -> DdsResult<()>

pub fn read(&self) -> DdsResult<bool>

Read the current trigger state without consuming it.

pub fn take(&self) -> DdsResult<bool>

Take (read and reset) the current trigger state.
