Trait Implementations§

source §

impl<S> FrameAllocator<S> for PhysicalMemoryManagerwhere S: FrameSize,

source §

fn allocate_n(&self, n: usize) -> Range<Frame<S>>

Allocate n contiguous Frames.

source §

Blanket Implementations§

source §

impl<T> Any for Twhere T: 'static + ?Sized,

source §

fn type_id(&self) -> TypeId

Gets the TypeId of self. Read more

source §

impl<T> Borrow<T> for Twhere T: ?Sized,

source §

fn borrow(&self) -> &T

Immutably borrows from an owned value. Read more

source §

impl<T> Downcast for Twhere T: Any,

source §

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

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

source §

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

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

source §

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

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

source §

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

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

source §

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

source §

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

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