| 39 | // A FileDiskRep represents a single code file on disk. We assume nothing about | |
| 40 | // the format or contents of the file and impose no structure on it, other than | |
| 41 | // assuming that all relevant code is contained in the file's data bytes. | |
| 42 | // By default, we seal the entire file data as a single page. | |
| 43 | // | |
| 44 | // This is the ultimate fallback disk format. It is used if no other pattern | |
| 45 | // applies. As such it is important that we do not introduce any assumptions | |
| 46 | // here. Know that you do not know what any of the file means. | |
