Struct dync::CopyValueMut

pub struct CopyValueMut<'a, V = ()> where
    V: ?Sized,  { /* fields omitted */ }

A generic mutable Copy value reference.

Implementations

impl<'a, V> CopyValueMut<'a, V>

pub fn new<T: Elem>(typed: &'a mut T) -> CopyValueMut<'a, V> where
    V: VTable<T>, 

Create a new CopyValueMut from a typed mutable reference.

impl<'a, V: ?Sized> CopyValueMut<'a, V>

pub fn size(&self) -> usize

Get the size of the value pointed-to by this reference.

pub fn value_type_id(&self) -> TypeId

Get the TypeId of the referenced value.

pub fn is<T: 'static>(&self) -> bool

Returns true if this referenced value's type is the same as T.

pub fn copy(self, other: CopyValueRef<'a, V>) -> Option<Self>

Copy value from other to self and return Self.

This function returns None if the values have different types.

pub fn swap(&mut self, other: &mut CopyValueMut<V>)

Swap the values between other and self.

pub fn downcast<T: Elem>(self) -> Option<&'a mut T>

Downcast this value reference into a borrowed T type. Return None if the downcast fails.

pub fn upcast<U: From<V>>(&mut self) -> CopyValueMut<U> where
    V: Clone,

fn fmt(&self, f: &mut Formatter) -> Result

Formats the value using the given formatter.

impl<'a, V: HasDrop> From<CopyValueMut<'a, V>> for CopyValueRef<'a, V>
