    Interface FileSystemProviderWithUpdateCapability

    Subtype of FileSystemProvider that ensures that the optional functions needed, for providers that should be able to update (text) files, are implemented.

    interface FileSystemProviderWithUpdateCapability {
        capabilities: FileSystemProviderCapabilities;
        onDidChangeCapabilities: Event<void>;
        onDidChangeFile: Event<readonly FileChange[]>;
        onFileWatchError: Event<void>;
        access?(resource: URI, mode?: number): Promise<void>;
        close?(fd: number): Promise<void>;
        copy?(from: URI, to: URI, opts: FileOverwriteOptions): Promise<void>;
