Struct AddressSpaceMembarrierId 

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

Stable identity of one Linux-style address-space generation.

Distinct scheduler resource tokens may carry different AddressSpaceHandle values while referring to the same shared mm. Runtime providers must therefore derive this identity from the shared address-space owner rather than from the token allocation itself.

Implementations

impl AddressSpaceMembarrierId

pub const NONE: Self

Identity used by kernel threads which do not own a userspace mm.

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

Creates an identity from a runtime-owned shared address-space object.

Safety

A non-zero value must remain unique for the complete lifetime of the corresponding address-space generation. It must not be reused while an AddressSpaceMembarrierState containing it can remain rq-visible.

pub const fn is_none(self) -> bool

Returns whether this is the kernel-thread sentinel.

pub const fn into_raw(self) -> usize

Returns the provider-owned opaque identity.
