TriggerContext

Struct TriggerContext 

Source
pub struct TriggerContext<'a> {
    pub store: Option<&'a dyn EpisodeStore>,
    pub event_count: Option<usize>,
    pub last_train_at: Option<u64>,
    pub last_train_count: usize,
    pub metrics: Option<&'a TriggerMetrics>,
}
Expand description

Trigger 判定のためのコンテキスト

§使い分け

  • LearnProcess(Episode ベース): store を指定、event_count は None
  • LearningSink(イベントベース): store は None、event_count を指定

Fields§

§store: Option<&'a dyn EpisodeStore>

Episode ストア(件数確認用、オプション)

§event_count: Option<usize>

直接指定のイベント/Episode 件数(EpisodeStore がない場合に使用)

§last_train_at: Option<u64>

最終学習時刻(Unix timestamp ms)

§last_train_count: usize

前回学習時の Episode 件数

§metrics: Option<&'a TriggerMetrics>

現在の品質メトリクス(オプション)

Implementations§

Source§

impl<'a> TriggerContext<'a>

Source

pub fn with_store(store: &'a dyn EpisodeStore) -> Self

EpisodeStore ベースのコンテキストを作成

Source

pub fn with_count(count: usize) -> Self

イベントカウントベースのコンテキストを作成(EpisodeStore 不要)

Source

pub fn last_train_at(self, timestamp: u64) -> Self

最終学習時刻を設定

Source

pub fn last_train_count(self, count: usize) -> Self

前回学習時の件数を設定

Source

pub fn metrics(self, metrics: &'a TriggerMetrics) -> Self

メトリクスを設定

Source

pub fn current_count(&self) -> Result<usize, TriggerError>
