[−][src]Crate lazy_futuristic
Initialize variables lazily.
Instead of requiring a closure to initialize the value, caller can acts based on returned ValueOrSetter
.
Example
use lazy_futuristic::Lazy; use lazy_futuristic::ValueOrSetter::*; let lazy_number: Lazy<i32> = Lazy::new(); let number = match lazy_number.get_or_set().await { Value(value) => value, Setter(setter) => setter.set(10), }; assert_eq!(*number, 10);
Structs
Lazy | Lazy variable. |
Setter | Setter of Lazy objects which also acts as Mutex guard. |
