Enum LazyWrapState

Source 
pub enum LazyWrapState<T, F> {
    Initialised(T),
    Uninitialised(F),
}
Expand description

Returned by LazyWrap::into_inner, containing the initialised value if its already initialised, or otherwise the initialisation function.

Variants§

§

Initialised(T)

Contains previously initialised value

§

Uninitialised(F)

Value is not initialised, contains initialisation function.
