Usage and interface (fastrw)

Documentation on exports (fastrw)

PREDICATE: fast_read/1:

fast_read(Term)

The next term is read from current standard input and is unified with Term. The syntax of the term must agree with fast_read / fast_write format. If the end of the input has been reached, Term is unified with the term 'end_of_file'. Further calls to fast_read/1 will then cause an error.

PREDICATE: fast_write/1:

fast_write(Term)

Output Term in a way that fast_read/1 and fast_read/2 will be able to read it back.

PREDICATE: fast_read/2:

fast_read(Stream, Term)

The next term is read from Stream and unified with Term. The syntax of the term must agree with fast_read / fast_write format. If the end of the input has been reached, Term is unified with the term 'end_of_file'. Further calls to fast_read/2 will then cause an error.

PREDICATE: fast_write/2:

fast_write(Stream, Term)

Output Term to Stream in a way that fast_read/1 and fast_read/2 will be able to read it back.

PREDICATE: fast_write_to_string/3:

No further documentation available for this predicate.

Known bugs and planned improvements (fastrw)

• Both fast_read/2 and fast_write/2 simply set the current output/input and call fast_read/1 and fast_write/1. Therefore, in the event an error hapens during its execution, the current input / output streams may be left pointing to the Stream
