Struct StackHandle 

pub struct StackHandle(/* private fields */);

Opaque handle to a runtime-owned stack allocation.

Implementations

impl StackHandle

pub const NONE: Self

Sentinel returned before the corresponding runtime object exists.

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::resource::StackHandle;
let _handle = StackHandle::from_raw(1);

pub const fn into_raw(self) -> usize

Returns the runtime-owned opaque value.

pub const fn is_none(self) -> bool

Returns whether this is the absent-handle sentinel.
