Struct Mrc 

pub struct Mrc<T> { /* private fields */ }

Atomic counted wrapper that updates a nonce counter on every mutable access of the inner content in an inner mutable container such as an RwLock or Mutex. It’s PartialEq behavior is reduced to comparing the memory location and counter index. For the potentially expensive true inner equality comparison, look for the implementation of inner_eq.

Implementations

impl<T> Mrc<T>

Generic Marc implementation.

pub fn new_refcell(value: T) -> Mrc<RefCell<T>>

Create a new Mrc with a RefCell governing interior mutability (for types that are Clone).

impl<T> Mrc<RefCell<T>>

RefCell backed Mrc implementation.

pub fn new(value: T) -> Self

Create a new Marc instance with an RwLock governing interior mutability.

Trait Implementations

impl<T> BorrowDeref<T> for Mrc<RefCell<T>>

fn borrow(&self) -> impl Deref<Target = T> + '_

Read only borrow.

impl<T> BorrowDerefMut<T> for Mrc<RefCell<T>>

fn borrow_mut(&self) -> impl DerefMut<Target = T> + '_

Mutably borrow the inner value.

impl<T> Clone for Mrc<T>

fn clone(&self) -> Self

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl<T: Debug> Debug for Mrc<T>

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

Formats the value using the given formatter.

impl<T: Default> Default for Mrc<T>

fn default() -> Self

Returns the “default value” for a type.

impl<'de, T: Deserialize<'de>> Deserialize<'de> for Mrc<RefCell<T>>

Available on crate feature serde only.

fn deserialize<D>(deserializer: D) -> Result<Self, D::Error>

where D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl<T> From<T> for Mrc<T>

fn from(value: T) -> Self

Converts to this type from the input type.

impl<T: PartialEq> InnerEq<T> for Mrc<RefCell<T>>

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

Compare the equality of a wrapped type.

impl<T> PartialEq for Mrc<T>

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<T: PartialOrd> PartialOrd for Mrc<RefCell<T>>

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.

impl<T: Serialize> Serialize for Mrc<RefCell<T>>

Available on crate feature serde only.

fn serialize<S>(&self, serializer: S) -> Result<S::Ok, S::Error>

where S: Serializer,

Serialize this value into the given Serde serializer.
