    Interface FileSystemProvider

    A FileSystemProvider provides the capabilities to read, write, discover, and to manage files and folders of the underlying (potentially virtual) file system. FileSystemProviders can be used to serve files from both the local disk as well as remote locations like ftp-servers, REST-services etc. A FileSystemProvider is registered for a certain scheme and can handle all resources whose uri does conform to that scheme.

    interface FileSystemProvider {
        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>;
        delete(resource: URI, opts: FileDeleteOptions): Promise<void>;
        fsPath?(resource: URI): Promise<string>;
        mkdir(resource: URI): Promise<void>;
        open?(resource: URI, opts: FileOpenOptions): Promise<number>;
        read?(
            fd: number,
            pos: number,
            data: Uint8Array,
            offset: number,
            length: number,
        ): Promise<number>;
        readdir(resource: URI): Promise<[string, FileType][]>;
        readFile?(resource: URI): Promise<Uint8Array>;
        readFileStream?(
            resource: URI,
            opts: FileReadStreamOptions,
            token: CancellationToken,
        ): ReadableStreamEvents<Uint8Array>;
        rename(from: URI, to: URI, opts: FileOverwriteOptions): Promise<void>;
        stat(resource: URI): Promise<Stat>;
        updateFile?(
            resource: URI,
            changes: TextDocumentContentChangeEvent[],
            opts: FileUpdateOptions,
        ): Promise<FileUpdateResult>;
        watch(resource: URI, opts: WatchOptions): Disposable;
        write?(
            fd: number,
            pos: number,
            data: Uint8Array,
            offset: number,
            length: number,
        ): Promise<number>;
        writeFile?(
            resource: URI,
            content: Uint8Array,
            opts: FileWriteOptions,
