Struct ManagedRef 

pub struct ManagedRef<T> { /* private fields */ }

Owning handle to a managed-memory region. Arc-cloned across agents; the underlying allocation is freed when the last clone drops.

Implementations

impl<T> ManagedRef<T>

pub fn is_valid(&self) -> bool

True if the underlying allocation is still live.

pub fn len(&self) -> usize

pub fn is_empty(&self) -> bool

pub fn as_ptr(&self) -> *const T

Raw device pointer. Valid for both host and device access while the allocator is alive. Caller is responsible for synchronization.

pub fn as_mut_ptr(&self) -> *mut T

impl<T: Copy> ManagedRef<T>

pub fn as_slice(&self) -> &[T]

Host-side immutable view of the managed memory.

SAFETY contract: managed memory is coherent host/device, but reads from the host before the device has finished writing produce undefined values. Caller must synchronize the relevant device stream first (e.g. via cudaDeviceSynchronize) when reading data the device wrote. Returns an empty slice if the allocator has stopped.

pub fn as_mut_slice(&mut self) -> &mut [T]

Host-side mutable view of the managed memory.

Like Self::as_slice this is a host alias of device-visible memory. The caller must hold a WriteToken (e.g. from crate::memory::ManagedAllocatorActor or SharedGpuStateCoordinator) to avoid concurrent device writes while writing from the host.

Trait Implementations

impl<T> Clone for ManagedRef<T>

fn clone(&self) -> Self

Returns a duplicate of the value.

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

Performs copy-assignment from source.
