Type Alias Once

pub type Once<T = ()> = Once<T>;

A primitive that provides lazy one-time initialization. See once::Once for documentation.

A note for advanced users: this alias exists to avoid subtle type inference errors due to the default relax strategy type parameter. If you need a non-default relax strategy, use the fully-qualified path.
