Enum doublysure::AreYouSure

pub enum AreYouSure<T> {
    Value(T),
    DeferredFunction(Box<dyn Fn() -> T>),
}

A type that asks the user the all important question: Are you sure you want to do this?

The functions on this type are intentionally verbose so that users understand that they are confirming a potentially destructive action.

Variants

Value(T)

A value that will be returned when yes_i_am_sure() is called.

DeferredFunction(Box<dyn Fn() -> T>)

A function that was deferred and will be run later when yes_i_am_sure() is called.

Implementations

impl<T> AreYouSure<T>

pub fn new(val: T) -> Self

Creates a new AreYouSure wrapping around a value. This is the same as AreYouSure::Value().

The make_sure macro is the preferred way of creating an AreYouSure.

pub fn yes_i_am_sure(self) -> T

You are, in fact, sure that you want to do this.

Returns the inner value, or runs the deferred function and returns whatever it does.

pub fn no_i_am_not_sure(self)

You're not actually sure you want to do this.

This will discard the AreYouSure dropping it's value and will not run deferred functions.
