Struct OpenedIpcMemory 

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

Implementations

impl<T> OpenedIpcMemory<T>

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

pub fn close(self) -> Result<()>

Decrements the reference count of the memory returned by IpcMemoryHandle::create_mapping by 1. When the reference count reaches 0, this unmaps the memory. The original allocation in the exporting process and imported mappings in other processes are unaffected.

Resources used to enable peer access are freed if this is the last mapping using them.

IPC is restricted to devices with support for unified addressing on Linux and Windows operating systems. IPC on Windows is supported for compatibility, but is not recommended because it has a performance cost. Check device IPC support through the device properties exposed by this crate, for example DeviceProperties::ipc_event_supported.

Additional CUDA diagnostics:

• This call may also return crate::error::Status::NotInitialized, crate::error::Status::CallRequiresNewerDriver, or crate::error::Status::NoDevice if it initializes internal CUDA runtime state.
• Callbacks must not call CUDA functions; see Stream::add_callback. crate::error::Status::NotPermitted may, but is not guaranteed to, be returned as a diagnostic in that case.

Errors

Returns an error if CUDA Runtime cannot close the imported mapping.

Trait Implementations

impl<T: Debug> Debug for OpenedIpcMemory<T>

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl<T> Drop for OpenedIpcMemory<T>

fn drop(&mut self)

Executes the destructor for this type.

fn pin_drop(self: Pin<&mut Self>)

🔬This is a nightly-only experimental API. (pin_ergonomics)

Execute the destructor for this type, but different to Drop::drop, it requires self to be pinned.
