Current state of a Once
.
Variants
New
A closure has not been executed yet
Poisoned
A closure was executed but panicked.
InProgress

Done

Methods
impl OnceState
[src]
pub fn poisoned(&self) -> bool
[src]
Returns whether the associated Once
has been poisoned.
Once an initalization routine for a Once
has panicked it will forever
indicate to future forced initialization routines that it is poisoned.
pub fn done(&self) -> bool
[src]
Returns whether the associated Once
has successfullly executed a
closure.
