Comparing Interface vs Type for RandomBytes Function

What do you prefer for a service? Interface with a function or just a function?

export interface RandomBytes {
  readonly next: (
    bytesLength: number,
  ) => Effect.Effect<never, never, Uint8Array>;
}

export interface RandomBytes {
  readonly next: (
    bytesLength: number,
  ) => Effect.Effect<never, never, Uint8Array>;
}

export type RandomBytes = (
  bytesLength: number,
) => Effect.Effect<never, never, Uint8Array>;

export type RandomBytes = (
  bytesLength: number,
) => Effect.Effect<never, never, Uint8Array>;
