Struct BoxAny VarValue &nbsp; Copy item path

impl BoxAnyVarValue

pub fn new(value: impl AnyVarValue) -> BoxAnyVarValue

Box value.

pub fn downcast<T>(self) -> Result<T, BoxAnyVarValue>
where T: VarValue,

Downcast to value.

pub fn type_id(&self) -> TypeId

Gets the TypeId of the boxed value.

Note that if you call Any::type_id directly on this type you will get the BoxAnyVarValue type id, not the id of the actual value.

pub fn detailed_debug(&self) -> impl Debug

Alternate formatter that writes detailed debug info about the box and value type name.

The std::fmt::Debug implementation simply redirects to the value debug, this wrapper provides more info.

Methods from Deref<Target = dyn AnyVarValue>§

pub fn downcast_ref<T>(&self) -> Option<&T>
where T: VarValue,

Returns some reference to the inner value if it is of type T, or None if it isn’t.

pub fn downcast_mut<T>(&mut self) -> Option<&mut T>
where T: VarValue,

Returns some mutable reference to the inner value if it is of type T, or None if it isn’t.

pub fn is<T>(&self) -> bool
where T: VarValue,

Returns true if the inner type is the same as T.

impl<T> CloneToUninit for T
where T: Clone,

unsafe fn clone_to_uninit(&self, dest: *mut u8)

🔬This is a nightly-only experimental API. (clone_to_uninit)

impl<T> Downcast for T
where T: Any,

fn into_any(self: Box<T>) -> Box<dyn Any>

Convert Box<dyn Trait> (where Trait: Downcast) to Box<dyn Any>. Box<dyn Any> can then be further downcast into Box<ConcreteType> where ConcreteType implements Trait.

fn into_any_rc(self: Rc<T>) -> Rc<dyn Any>

Convert Rc<Trait> (where Trait: Downcast) to Rc<Any>. Rc<Any> can then be further downcast into Rc<ConcreteType> where ConcreteType implements Trait.

fn as_any(&self) -> &(dyn Any + 'static)

Convert &Trait (where Trait: Downcast) to &Any. This is needed since Rust cannot generate &Any’s vtable from &Trait’s.

fn as_any_mut(&mut self) -> &mut (dyn Any + 'static)

Convert &mut Trait (where Trait: Downcast) to &Any. This is needed since Rust cannot generate &mut Any’s vtable from &mut Trait’s.

impl<T> DowncastSync for T
where T: Any + Send + Sync,

fn into_any_arc(self: Arc<T>) -> Arc<dyn Any + Sync + Send>

Convert Arc<Trait> (where Trait: Downcast) to Arc<Any>. Arc<Any> can then be further downcast into Arc<ConcreteType> where ConcreteType implements Trait.

impl<T> From<T> for T

fn from(t: T) -> T

Returns the argument unchanged.

impl<T> FsChangeNote for T
where T: Debug + Any + Send + Sync,

fn as_any(&self) -> &(dyn Any + 'static)

Access any.
