Struct Transition 

pub struct Transition<State, Effect> { /* private fields */ }

English:
Owned next state and ordered effect descriptions returned by a ProcessManager. Construction and access do not execute effects or persist the state. Empty effects are valid; callers choose how to coordinate state storage and effect execution.

Inspect the transition before taking ownership of both components.

日本語:
ProcessManager が返す、所有された次状態と順序付きの副作用の記述です。 構築や参照で副作用を実行したり状態を永続化したりしません。空の副作用列も許容し、 状態保存と副作用実行の連携方法は呼び出し側が決めます。

遷移を参照してから、両方の構成要素の所有権を取り出します。

Example / 使用例

use ddd_toolkit_core::Transition;

let transition = Transition::new("paid", vec!["send receipt"]);
assert_eq!(transition.state(), &"paid");
assert_eq!(transition.effects(), &["send receipt"]);
let (state, effects) = transition.into_parts();
assert_eq!((state, effects), ("paid", vec!["send receipt"]));

Implementations

impl<State, Effect> Transition<State, Effect>

pub fn new(state: State, effects: Vec<Effect>) -> Transition<State, Effect>

English:
Stores state and effects unchanged, preserving the vector’s order without validation.

日本語:
検証せず、ベクターの順序を保ったまま state と effects を保持します。

pub fn state(&self) -> &State

English:
Borrows the next state without applying it to any external store.

日本語:
外部ストアへの反映を行わず、次状態を借用します。

pub fn effects(&self) -> &[Effect]

English:
Borrows the effect descriptions in their stored order without executing them.

日本語:
実行せず、保持している順序で副作用の記述を借用します。

pub fn into_parts(self) -> (State, Vec<Effect>)

English:
Consumes the transition to return its state and effect vector without cloning.

日本語:
遷移を消費し、複製せずに状態と副作用のベクターを返します。
