	Construct a new memory base stream. More...

	MemStream (const MemStream &f)=delete

MemStream &	operator= (const MemStream &)=delete

virtual or_error	open () override
	open the file

virtual int	close () override
	close the file

virtual int	seek (off_t offset, int whence) override
	seek in the file. Semantics are similar to POSIX lseek()

virtual int	read (void *buf, size_t count) override
	read in the file. Semantics are similar to POSIX read()

virtual off_t	filesize () override
	Return the filesize.

Error	get_error () const
	Obtain the last error.

const std::string &	get_path () const
	Get the uri path of the file.

uint8_t	readByte () noexcept(false)
	Read a single byte.
