fn sendFile(w: *Writer, file_reader: *File.Reader, limit: Limit) FileError!usizeReadFailedDetailed diagnostics are found on the File.Reader struct.
WriteFailedSee the Writer implementation for detailed diagnostics.
EndOfStreamReached the end of the file being read.
UnimplementedIndicates the caller should do its own file reading; the callee cannot offer a more efficient implementation.
