Struct hydroflow::scheduled::state::StateHandleErased

pub struct StateHandleErased { /* private fields */ }

A state handle with the generic type parameter erased, allowing it to be stored in omogenous data structures. The type is tracked internally as data via TypeId.

Use StateHandleErased::from(state_handle) to create an instance from a typed StateHandle<T>.

Use StateHandle::<T>::try_from() to convert the StateHandleErased back into a StateHandle<T> of the given type T. If T is the wrong type then the original StateHandleErased will be returned as the Err.

Trait Implementations

impl Clone for StateHandleErased

fn clone(&self) -> StateHandleErased

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for StateHandleErased

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

Formats the value using the given formatter.

impl<T> From<StateHandle<T>> for StateHandleErased

where T: Any,

See StateHandleErased.

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

Converts to this type from the input type.

impl Hash for StateHandleErased

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 StateHandleErased

fn cmp(&self, other: &StateHandleErased) -> 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 StateHandleErased

fn eq(&self, other: &StateHandleErased) -> 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 StateHandleErased

fn partial_cmp(&self, other: &StateHandleErased) -> 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> TryFrom<StateHandleErased> for StateHandle<T>

where T: Any,

See StateHandleErased.

type Error = StateHandleErased

The type returned in the event of a conversion error.

fn try_from(value: StateHandleErased) -> Result<Self, Self::Error>

Performs the conversion.
