Struct xlang_abi::traits::DynRef

#[repr(C)]
pub struct DynRef<'lt, T: ?Sized + AbiSafeTrait> { /* private fields */ }

An Abi safe wrapper arround a shared reference to a trait object

Implementations

impl<'lt, T: ?Sized + AbiSafeTrait> DynRef<'lt, T>

pub fn as_pinned(x: &Pin<Self>) -> Pin<&(dyn DynPtrSafe<T> + 'lt)>

Derefences x inside a pin

pub fn unsize_ref<U>(x: &'lt U) -> Selfwhere
    T: AbiSafeUnsize<U>,

Unsizes a shared reference into a DynRef to T

Trait Implementations

impl<'lt, T: ?Sized + AbiSafeTrait> Allocator for DynRef<'lt, T>where
    dyn DynPtrSafe<T> + 'lt: Allocator,

fn allocate(&self, layout: Layout) -> Option<NonNull<u8>>

Allocates memory suitable for layout, and returns a pointer to it, or None if an error occurs. The value of the memory accessed via the pointer is uninitialized

unsafe fn deallocate(&self, ptr: NonNull<u8>, layout: Layout)

Deallocates Memory obtained from a call to Allocator::allocate with the given layout

fn allocate_zeroed(&self, layout: Layout) -> Option<NonNull<u8>>

Allocates memory suitable for layout, and returns a pointer to it, or None if an error occurs. Each byte pointed to by the return value up to layout.size() is 0

unsafe fn grow(
    &self,
    ptr: NonNull<u8>,
    old_layout: Layout,
    new_layout: Layout
) -> Option<NonNull<u8>>

Grows an allocation given by ptr and old_layout, copying the data from the old allocation into the new allocation. ptr may not be used to access memory after a call to this function. It is unsound to call grow on core::pin::Pinned memory

unsafe fn grow_zeroed(
    &self,
    ptr: NonNull<u8>,
    old_layout: Layout,
    new_layout: Layout
) -> Option<NonNull<u8>>

Grows an allocation given by ptr and old_layout, copying the data from the old allocation into the new allocation. ptr may not be used to access memory after a call to this function. It is unsound to call grow_zeroed on core::pin::Pinned memory

unsafe fn shrink(
    &self,
    ptr: NonNull<u8>,
    old_layout: Layout,
    new_layout: Layout
) -> Option<NonNull<u8>>

Grows an allocation given by ptr and old_layout, copying the data from the old allocation into the new allocation. ptr may not be used to access memory after a call to this function. It is unsound to call shrink on core::pin::Pinned memory

fn as_ref(&self) -> &Selfwhere
    Self: Sized,

Returns exactly self

impl<'lt, T: ?Sized + AbiSafeTrait> Clone for DynRef<'lt, T>

fn clone(&self) -> Self

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl<'lt, T: ?Sized + AbiSafeTrait> Deref for DynRef<'lt, T>

type Target = dyn DynPtrSafe<T> + 'lt

The resulting type after dereferencing.

fn deref(&self) -> &Self::Target

Dereferences the value.

impl<'lt, T: ?Sized + AbiSafeTrait> Copy for DynRef<'lt, T>

impl<'lt, T: ?Sized + AbiSafeTrait + Sync> Send for DynRef<'lt, T>

impl<'lt, T: ?Sized + AbiSafeTrait + Sync> Sync for DynRef<'lt, T>
