[−][src]Enum abi_stable::external_types::parking_lot::once::ROnceState
Describes the running state of an ROnce.
Variants
An ROnce that hasn't started running
An ROnce that panicked inside call_once*
An ROnce that is the middle of calling call_once*
An ROnce that has already run.
Implementations
impl ROnceState[src]
pub fn poisoned(&self) -> bool[src]
Whether the ROnce is poisoned,requiring call_once_force to run.
Example
use abi_stable::external_types::ROnce; use std::panic::AssertUnwindSafe; let once=ROnce::new(); let _=std::panic::catch_unwind(AssertUnwindSafe(||{ once.call_once(|| panic!() ); })); assert!(once.state().poisoned());
pub fn done(&self) -> bool[src]
Whether the ROnce has already finished running.
Example
use abi_stable::external_types::ROnce; let once=ROnce::new(); once.call_once(|| () ); assert!(once.state().done());
