interface TileStore<Tile> {

    get(sourceId: string, key: string): Tile | undefined;
    drop(sourceId: string): void;

名前	型	説明
`want`	`(source: TileLoader<Tile>, keys: readonly string[], again?: boolean): ReadonlyMap<string, Tile>`	Tells the store which tiles `source` needs now, and returns the ones it holds. When the keys are the same as the last call it does nothing, so a view that asks again at rest sends nothing; when they changed, the missing ones load (a tile that failed is tried again only now), the loads of tiles no longer needed are aborted, and the held ones are marked used. `again: true` is for a caller that means "try what is missing once more" with the same keys: it starts the missing tiles that are not already loading or waiting, and nothing else changes.
`get`	`(sourceId: string, key: string): Tile \| undefined`	One held tile, or `undefined`.
`drop`	`(sourceId: string): void`	Forgets a source: aborts its loads, frees its tiles. The source is switched off.
`stats`	`(): TileStats`
`idle`	`(): Promise<void>`	Resolves when no load is running or waiting.

例

import type { TileStore } from "./data-door.ts";

const held = (store: TileStore<Uint8Array>): number => store.stats().held;
