Struct PhaseStateStore 

pub struct PhaseStateStore { /* private fields */ }

Stores serialized phase state for nodes, keyed by phase enum TypeId.

Phase enums generated by macros implement Serialize + Deserialize. The store serializes them to bytes on set() and deserializes on get(), so the store itself is serializable without generic parameters.

Example

let mut store = PhaseStateStore::new();
store.set::<MyPhase>(&MyPhase::GatherMore { position })?;
let phase: MyPhase = store.get::<MyPhase>()?.unwrap();

Implementations

impl PhaseStateStore

pub fn new() -> Self

Create an empty phase state store.

pub fn set<T>(&mut self, value: &T) -> Result<(), PhaseStoreError>

where T: Serialize + 'static,

Store a phase value, serializing it to bytes.

Overwrites any existing phase of the same type.

pub fn get<T>(&self) -> Result<Option<T>, PhaseStoreError>

where T: for<'de> Deserialize<'de> + 'static,

Retrieve and deserialize a phase value by type.

Returns None if no phase of this type is stored.

pub fn clear<T: 'static>(&mut self)

Remove the phase state for a given type (used on complete).

pub fn contains<T: 'static>(&self) -> bool

Whether the store contains a phase of the given type.

pub fn is_empty(&self) -> bool

Whether the store is empty (no phases stored).
