Struct BackingIdentity 

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

BackingIdentity

Identity of a physical backing allocation, shared by all of its wrappers. This is host custody metadata, not a virtual memory ID or durable record.

Implementations

impl BackingIdentity

pub fn of_rc<T: ?Sized>(backing: &Rc<T>) -> Self

Identify an Rc-owned backing. Its allocation must remain alive through every runtime/handle using this identity. Identify the underlying backing, not a newly allocated wrapper or an address inside a growable byte buffer.

pub fn of_arc<T: ?Sized>(backing: &Arc<T>) -> Self

Identify an Arc-owned backing under the same contract as Self::of_rc.

Trait Implementations

impl Clone for BackingIdentity

fn clone(&self) -> Self

impl Eq for BackingIdentity

impl Ord for BackingIdentity

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.

fn clamp_to<R>(self, range: R) -> Self

where Self: Sized, R: ClampBounds<Self>,

🔬This is a nightly-only experimental API. (clamp_to)

Restrict a value to a certain range.

impl PartialEq for BackingIdentity

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

Equality operator ==.

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

Inequality operator !=.

impl PartialOrd for BackingIdentity

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.
