Trait Implementations

impl Clone for SharedReference

fn clone(&self) -> SharedReference

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for SharedReference

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

Formats the value using the given formatter.

impl Display for SharedReference

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

Formats the value using the given formatter.

impl From<SharedReference> for CellContent

fn from(value: SharedReference) -> Self

Converts to this type from the input type.

impl<T: Send + Sync + 'static> From<TransientInstance<T>> for SharedReference

fn from(instance: TransientInstance<T>) -> Self

Converts to this type from the input type.

impl Hash for SharedReference

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 SharedReference

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 PartialEq for SharedReference

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 PartialOrd for SharedReference

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 TryFrom<CellContent> for SharedReference

type Error = CellContent

The type returned in the event of a conversion error.

fn try_from(content: CellContent) -> Result<Self, CellContent>

Performs the conversion.

impl<T: Send + Sync + 'static> TryFrom<SharedReference> for TransientInstance<T>

type Error = ()

The type returned in the event of a conversion error.

fn try_from(inner: SharedReference) -> Result<Self, Self::Error>

Performs the conversion.
