Struct CombRc 

pub struct CombRc<T: Clone> { /* private fields */ }

A wrapper around an Rc that clones when mutably borrowed if it is not unique.

Like Rc, this is not thread-safe.

Examples

See the crate documentation for examples.

Implementations

impl<T: Clone> CombRc<T>

pub fn new(what: T) -> CombRc<T>

Constructs a CombRc.

pub fn from_rc(what: Rc<T>) -> CombRc<T>

Constructs a CombRc from an already created Rc.

pub fn clone_unique(what: &CombRc<T>) -> CombRc<T>

Clones the inner value stored in the CombRc, returning a unique clone of it.

pub fn try_unwrap(what: CombRc<T>) -> Result<T, Self>

Attempt to get the inner value inside of the CombRc.

If this is a unique reference, the inner value will be moved. Otherwise, the reference will be re-returned.

pub fn make_inner(what: CombRc<T>) -> T

Try to get the inner value inside of the CombArc or clone otherwise.

If this is a unique reference, the inner value will be moved. Otherwise, it will be cloned.

pub fn get_rc(what: &CombRc<T>) -> &Rc<T>

Get the inner Rc value.

Trait Implementations

impl<T: Clone + Clone> Clone for CombRc<T>

fn clone(&self) -> CombRc<T>

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl<T: Debug + Clone> Debug for CombRc<T>

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

Formats the value using the given formatter.

impl<T: Default + Clone> Default for CombRc<T>

fn default() -> CombRc<T>

Returns the “default value” for a type.

impl<T: Clone> Deref for CombRc<T>

type Target = T

The resulting type after dereferencing.

fn deref(&self) -> &T

Dereferences the value.

impl<T: Clone> DerefMut for CombRc<T>

fn deref_mut(&mut self) -> &mut T

If the inner Rc has no strong references, get a mutable reference. Otherwise, clone the Rc.

This just calls Rc::make_mut on the inner value.

impl<T: Display + Clone> Display for CombRc<T>

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

Formats the value using the given formatter.

impl<T: Clone> From<CombRc<T>> for Rc<T>

fn from(value: CombRc<T>) -> Self

Converts to this type from the input type.

impl<T: Clone> From<Rc<T>> for CombRc<T>

fn from(value: Rc<T>) -> Self

Converts to this type from the input type.

impl<T: Ord + Clone> Ord for CombRc<T>

fn cmp(&self, other: &CombRc<T>) -> 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: Clone + PartialEq> PartialEq<T> for CombRc<T>

fn eq(&self, other: &T) -> 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: PartialEq + Clone> PartialEq for CombRc<T>

fn eq(&self, other: &CombRc<T>) -> 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: Clone + PartialOrd> PartialOrd<T> for CombRc<T>

fn partial_cmp(&self, other: &T) -> 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: PartialOrd + Clone> PartialOrd for CombRc<T>

fn partial_cmp(&self, other: &CombRc<T>) -> 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.
