Struct SCell 

pub struct SCell<T: ?Sized>(/* private fields */);

A smart container for objects in recursive data structures

This container contains Rc and therefore clone() will create a new reference to the same instance.

Implementations

impl<T> SCell<T>

pub fn new(t: T) -> Self

impl<T: ?Sized> SCell<T>

pub fn borrow(&self) -> Ref<'_, T>

pub fn borrow_mut(&self) -> RefMut<'_, T>

Trait Implementations

impl<T: ?Sized> Clone for SCell<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 for SCell<T>

where T: Debug + ?Sized,

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

Formats the value using the given formatter.

impl<T: Default + ?Sized> Default for SCell<T>

fn default() -> SCell<T>

Returns the “default value” for a type.

impl<T> Display for SCell<T>

where T: Display + ?Sized,

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

Formats the value using the given formatter.

impl<T> Eq for SCell<T>

where T: Eq + ?Sized,

impl<T> From<T> for SCell<T>

fn from(t: T) -> Self

Converts to this type from the input type.

impl<T> Hash for SCell<T>

where T: Hash + ?Sized,

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

where H: Hasher,

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<T> Ord for SCell<T>

where T: Ord + ?Sized,

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<T> PartialEq for SCell<T>

where T: PartialEq + ?Sized,

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

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

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

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

impl<T> PartialOrd for SCell<T>

where T: PartialOrd + ?Sized,

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: &Self) -> bool

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

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

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

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

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

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

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

impl<T: ?Sized> Pointer for SCell<T>

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

Formats the value using the given formatter.
