Required Associated Constants

const KEY: &'static str

Provided Associated Constants

const MERGE: MergeStrategy = MergeStrategy::Exclusive

Parallel merge strategy. Default: Exclusive (conflict on concurrent writes).

const SCOPE: KeyScope = KeyScope::Run

Lifetime scope. Default: Run (cleared at run start).

Required Associated Types

type Value: Clone + Default + Serialize + DeserializeOwned + Send + Sync + 'static

type Update: Send + 'static

Required Methods

fn apply(value: &mut Self::Value, update: Self::Update)

Provided Methods

fn encode(value: &Self::Value) -> Result<Value, StateError>

fn decode(value: Value) -> Result<Self::Value, StateError>

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
