iofree package¶
iofree is an easy-to-use and powerful library to help you implement network protocols and binary parsers.
-
class
iofree.
Parser
(gen: Generator)[source]¶ Bases:
object
-
property
has_result
¶
-
respond
(*, data: bytes = b'', close: bool = False, exc: Optional[Exception] = None, result: Any = <object object>) → None[source]¶ produce some event data to interact with a stream: data: bytes to send to the peer close: whether the socket should be closed exc: raise an exception to break the loop result: result to return
-
property
-
iofree.
get_parser
() → iofree.Parser[source]¶ get current parser object
-
iofree.
parser
(generator_func: Generator) → Generator[source]¶ decorator function to wrap a generator
-
iofree.
peek
(nbytes: int = 1, *, from_=None) → bytes[source]¶ peek many bytes without taking them away from buffer
-
iofree.
read
(nbytes: int = 0, *, from_=None) → bytes[source]¶ if nbytes = 0, read as many as possible, empty bytes is valid; if nbytes > 0, read exactly
nbytes
-
iofree.
read_int
(nbytes: int, byteorder: str = 'big', *, signed=False, from_=None) → int[source]¶ read some bytes as integer
-
iofree.
read_raw_struct
(struct_obj: Struct, *, from_=None) → tuple[source]¶ read raw struct formatted data
-
iofree.
read_until
(data: bytes, *, return_tail: bool = True, from_=None) → bytes[source]¶ read until some bytes appear
