Struct Handle 

#[repr(C)]
pub struct Handle {
    pub id: u32,
    pub generation: u32,
}

A generic handle to a kernel object.

Handles are unforgeable kernel-managed tokens that identify resources. The generation counter prevents use-after-free attacks when handles are recycled after object destruction.

Fields

id: u32

Unique identifier within the object pool.

generation: u32

Generation counter for stale handle detection. Incremented each time the slot is reused.

Implementations

impl Handle

pub const fn new(id: u32, generation: u32) -> Self

Creates a new handle with the given id and generation.

pub const fn null() -> Self

Creates a null handle (invalid).

pub const fn is_null(&self) -> bool

Checks if this handle is null (invalid).

pub const fn to_raw(&self) -> u64

Returns the raw 64-bit representation of this handle.

pub const fn from_raw(raw: u64) -> Self

Creates a handle from a raw 64-bit representation.

Trait Implementations

impl Clone for Handle

fn clone(&self) -> Handle

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Handle

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

Formats the value using the given formatter.

impl Default for Handle

fn default() -> Self

Returns the “default value” for a type.

impl Hash for Handle

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl PartialEq for Handle

fn eq(&self, other: &Handle) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
