Trait Implementations

impl<T: Clone> Clone for UntypedState<T>

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

Returns a copy of the value.

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

Performs copy-assignment from source.

impl<T: Debug> Debug for UntypedState<T>

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

Formats the value using the given formatter.

impl<K, V, T, D> From<TypedState<K, V, T, D>> for UntypedState<T>

where K: Codec, V: Codec, T: Codec64, D: Codec64,

fn from(typed_state: TypedState<K, V, T, D>) -> Self

Converts to this type from the input type.

impl<T: PartialEq> PartialEq for UntypedState<T>

fn eq(&self, other: &UntypedState<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.
