Trait Implementations

impl Clone for StateValue

fn clone(&self) -> StateValue

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for StateValue

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for StateValue

fn from(s: &str) -> Self

Converts to this type from the input type.

impl From<HashMap<String, StateValue>> for StateValue

fn from(obj: HashMap<String, StateValue>) -> Self

Converts to this type from the input type.

impl From<StateValue> for Value

Available on crate feature serde only.

fn from(value: StateValue) -> Self

Converts to this type from the input type.

impl From<String> for StateValue

fn from(s: String) -> Self

Converts to this type from the input type.
