Required Methods

source

fn to_ref(&self) -> Result<BoxRef<T>>

Get the reference to the underlying value without dropping it.

source

fn take_value(&self) -> Result<T>

Take the value out of the box.

source

fn release(self)

Provided Methods

source

fn with_ref<R, F>(&self, op: F) -> Result<R>where
F: FnOnce(&T) -> R,

Evaluate a given function with a reference to the boxed value. The lifetime of the reference can not outlive the closure.

source

fn with_clone<R, F>(&self, op: F) -> Result<R>where
F: FnOnce(T) -> R,
T: Clone,

Evaluate a given function with a clone of the boxed value. The boxed type T must implement Clone.

source

fn has_value(&self) -> bool

source

fn get_ptr(&self) -> *const T
