Miscellaneous native operations
|
||
|
|
===============================
|
||
|
|
|
||
|
|
This is a list of various non-type-specific operations that have
|
||
|
|
custom native implementations. If an operation has no native
|
||
|
|
implementation, mypyc will use fallback generic implementations that
|
||
|
|
are often not as fast.
|
||
|
|
|
||
|
|
.. note::
|
||
|
|
|
||
|
|
Operations specific to various primitive types are described
|
||
|
|
in the following sections.
|
||
|
|
|
||
|
|
Operators
|
||
|
|
---------
|
||
|
|
|
||
|
|
* ``x is y`` (this is very fast for all types)
|
||
|
|
|
||
|
|
Functions
|
||
|
|
---------
|
||
|
|
|
||
|
|
* ``isinstance(obj, type: type)``
|
||
|
|
* ``isinstance(obj, type: tuple)``
|
||
|
|
* ``cast(<type>, obj)``
|
||
|
|
* ``type(obj)``
|
||
|
|
* ``len(obj)``
|
||
|
|
* ``abs(obj)``
|
||
|
|
* ``id(obj)``
|
||
|
|
* ``iter(obj)``
|
||
|
|
* ``next(iter: Iterator)``
|
||
|
|
* ``hash(obj)``
|
||
|
|
* ``getattr(obj, attr)``
|
||
|
|
* ``getattr(obj, attr, default)``
|
||
|
|
* ``setattr(obj, attr, value)``
|
||
|
|
* ``hasattr(obj, attr)``
|
||
|
|
* ``delattr(obj, name)``
|
||
|
|
* ``slice(start, stop, step)``
|
||
|
|
* ``globals()``
|
||
|
|
|
||
|
|
Method decorators
|
||
|
|
-----------------
|
||
|
|
|
||
|
|
* ``@property``
|
||
|
|
* ``@staticmethod``
|
||
|
|
* ``@classmethod``
|
||
|
|
* ``@abc.abstractmethod``
|
||
|
|
|
||
|
|
Statements
|
||
|
|
----------
|
||
|
|
|
||
|
|
These variants of statements have custom implementations:
|
||
|
|
|
||
|
|
* ``for ... in seq:`` (for loop over a sequence)
|
||
|
|
* ``for ... in enumerate(...):``
|
||
|
|
* ``for ... in zip(...):``
|
