CurrentCpuLocalHandle

Struct CurrentCpuLocalHandle 

Source
pub struct CurrentCpuLocalHandle(/* private fields */);
Expand description

Opaque address of the current CPU’s pinned owner-only scheduler object.

Consumers must claim the corresponding crate::runtime::cpu::CpuRemote owner gate before reconstructing any reference from this address.

Implementations§

Source§

impl CurrentCpuLocalHandle

Source

pub const NONE: Self

Sentinel returned before the corresponding runtime object exists.

Source

pub const unsafe fn from_raw(raw: usize) -> Self

Creates a handle from the runtime-owned opaque value.

§Safety

A non-zero raw value must identify a live runtime-owned object or resource of this exact handle type. The caller must uphold all provenance, lifetime, pinning, aliasing, and ownership invariants required by operations that consume or dereference the handle. Use Self::NONE for the absent-handle sentinel.

use ax_task::runtime::cpu::CurrentCpuLocalHandle;
let _handle = CurrentCpuLocalHandle::from_raw(1);
Source

pub const fn into_raw(self) -> usize

Returns the runtime-owned opaque value.

Source

pub const fn is_none(self) -> bool

Returns whether this is the absent-handle sentinel.
