[−][src]Struct dync::CopyValueMut
A generic mutable Copy
value reference.
Implementations
impl<'a, V> CopyValueMut<'a, V>
[src]
pub fn new<T: Elem>(typed: &'a mut T) -> CopyValueMut<'a, V> where
V: VTable<T>,
[src]
V: VTable<T>,
Create a new CopyValueMut
from a typed mutable reference.
impl<'a, V: ?Sized> CopyValueMut<'a, V>
[src]
pub fn size(&self) -> usize
[src]
Get the size of the value pointed-to by this reference.
pub fn value_type_id(&self) -> TypeId
[src]
Get the TypeId
of the referenced value.
pub fn is<T: 'static>(&self) -> bool
[src]
Returns true
if this referenced value's type is the same as T
.
pub fn copy(self, other: CopyValueRef<'a, V>) -> Option<Self>
[src]
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>)
[src]
Swap the values between other
and self
.
pub fn downcast<T: Elem>(self) -> Option<&'a mut T>
[src]
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,
[src]
V: Clone,
