Shouldn't the enums and interfaces be exported?

My code cannot fully use these declarations as they are not exported:

declare type Format = "svg" | "dot" | "json" | "dot_json" | "xdot_json" | "plain" | "plain-ext";
declare type Engine = "circo" | "dot" | "fdp" | "sfdp" | "neato" | "osage" | "patchwork" | "twopi";
interface Image {
    path: string;
    width: string;
    height: string;
}
interface File {
    path: string;
    data: string;
}
interface Ext {
    images?: Image[];
    files?: File[];
    wasmFolder?: string;
    wasmBinary?: Uint8Array;
    yInvert?: boolean;
    nop?: number;
}

Is that an oversight or do I not understand how to use the library? Background: I am creating a wrapper for your Wasm that will fit my needs (based on JSON output) and I realised that I cannot create a wrapper with the same types as these types aren't exported.
