Struct IdPin 

pub struct IdPin<'a> { /* private fields */ }

🫆 🧺 A unique identifier based on a pinned stack-allocated reference.

---

^{📍 data/id}

---

IdPin generates a unique ID by pinning a value on the stack, ensuring that the ID is based on the stack memory address for the lifetime of the reference.

It doesn’t implement Clone or Default.

Examples

let mut data1: u8 = 0;
let id1 = IdPin::new(&mut data1);

Vendored

This is adapted work from object-id.

Implementations

impl<'a> IdPin<'a>

pub fn new(data: &'a mut u8) -> Self

Creates a new IdPin with a unique stack memory address.

Expects a mutable reference to a u8 data that will be pinned.

pub fn as_usize(&self) -> usize

Returns the unique ID as a usize, derived from the stack memory address.

Trait Implementations

impl<'a> Debug for IdPin<'a>

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

Formats the value using the given formatter.

impl Eq for IdPin<'_>

impl<'a> Hash for IdPin<'a>

fn hash<__H: Hasher>(&self, s: &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 Ord for IdPin<'_>

fn cmp(&self, other: &Self) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Self

where Self: Sized,

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Self

where Self: Sized,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Self

where Self: Sized,

Restrict a value to a certain interval.

impl PartialEq for IdPin<'_>

fn eq(&self, other: &Self) -> 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.

impl PartialOrd for IdPin<'_>

fn partial_cmp(&self, other: &Self) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

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

Tests less than (for self and other) and is used by the < operator.

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

Tests less than or equal to (for self and other) and is used by the <= operator.

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

Tests greater than (for self and other) and is used by the > operator.

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

Tests greater than or equal to (for self and other) and is used by the >= operator.
