Trait imply_option::ImplyOption

pub trait ImplyOption<T: Sized>: Sized + PartialEq<bool> {
    fn then(self, value: T) -> Option<T> { ... }
    fn then_do(
        self, 
        value: impl FnOnce() -> T
    ) -> Option<T> { ... }
}

Allows construction of an Option<T> based on a bool.

Provided Methods

fn then(self, value: T) -> Option<T>

If self == true returns Some(value).

fn then_do(
    self,
    value: impl FnOnce() -> T
) -> Option<T>

If self == true returns Some(value) where value is lazily constructed.
