Struct objc2::mutability::InteriorMutable

pub struct InteriorMutable { /* private fields */ }

Marker type for classes that use interior mutability.

This is usually not Send + Sync, unless the class is guaranteed to use thread-safe operations.

Functionality that is provided with this:

• IsRetainable -> ClassType::retain.
• IsIdCloneable -> Retained::clone.
• IsAllocableAnyThread -> ClassType::alloc.

Safety notice

When declaring classes, it is recommended that you wrap your instance variables in Cell, RefCell, atomics or other similar interior mutability abstractions to allow mutating your instance variables through &self.

Declared classes that use this cannot take &mut self, except in initializers.

Trait Implementations

impl Clone for InteriorMutable

fn clone(&self) -> InteriorMutable

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for InteriorMutable

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

Formats the value using the given formatter.

impl Hash for InteriorMutable

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 Ord for InteriorMutable

fn cmp(&self, other: &InteriorMutable) -> 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 + PartialOrd,

Restrict a value to a certain interval.

impl PartialEq for InteriorMutable

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

This method tests for self and other values to be equal, and is used by ==.

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

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

impl PartialOrd for InteriorMutable

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

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

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

This method tests less than (for self and other) and is used by the < operator.

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

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

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

This method tests greater than (for self and other) and is used by the > operator.

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

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