Function make

repos/effect/packages/effect/src/ConfigProvider.ts:400–402

(get: (path: Path) => Effect.Effect<Node | undefined, SourceError>)

 * The `get` callback receives a `Path` and must return
 * `Effect<Node | undefined, SourceError>`. Return `undefined` when the path does
 * not exist, a `Node` when it does, and fail with `SourceError` only when the
 * source cannot be read.
 *
 * Providers created by `make` also implement the path-transformation
 * capability used by {@link mapInput}, {@link constantCase}, and
 * {@link nested}.
