Trait BehaviorStore 

pub trait BehaviorStore: Debug + Send {
    // Required methods
    fn read(&self) -> Option<BehaviorState>;
    fn write(&self, state: &BehaviorState);
}

Where a host keeps persisted behavior state.

Read once when the world starts and written after any tick a save node ran in. A world whose host installs no store runs its behaviors and persists nothing.

Required Methods

fn read(&self) -> Option<BehaviorState>

The stored state, or None when nothing was stored or it could not be read.

fn write(&self, state: &BehaviorState)

Store state, replacing whatever was there. Only the implementor knows what the write was to, so reporting a failure is its job.

Dyn Compatibility

This trait is dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety".
