[−][src]Enum parking_lot::OnceState

[+] Show declaration

pub enum OnceState {
    New,
    Poisoned,
    InProgress,
    Done,
}

[−]

Current state of a Once.

Variants

New

[−]

A closure has not been executed yet

Poisoned

[−]

A closure was executed but panicked.

InProgress

[−]

A thread is currently executing a closure.

Done

[−]

A closure has completed successfully.

Methods

`impl OnceState`[src][−]

`pub fn poisoned(&self) -> bool`[src][−]

Returns whether the associated Once has been poisoned.

Once an initialization 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 successfully executed a closure.
