sourcepub fn value_type_id(&self) -> TypeId
pub fn value_type_id(&self) -> TypeId
Get the TypeId
of the referenced value.
sourcepub fn value_alignment(&self) -> usize
pub fn value_alignment(&self) -> usize
Get the alignment of the referenced value.
sourcepub fn is<T: 'static>(&self) -> bool
pub fn is<T: 'static>(&self) -> bool
Returns true
if this referenced value’s type is the same as T
.
sourcepub fn copy(self, other: CopyValueRef<'a, V>) -> Option<Self>
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.
sourcepub fn swap(&mut self, other: &mut CopyValueMut<'_, V>)
pub fn swap(&mut self, other: &mut CopyValueMut<'_, V>)
Swap the values between other
and self
.
sourcepub fn downcast<T: CopyElem>(self) -> Option<&'a mut T>
pub fn downcast<T: CopyElem>(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,
