Trait that contains methods

Provided Methods

fn hasattr<N>(&self, py: Python, attr_name: N) -> PyResult<bool> where N: ToPyObject

Determines whether this object has the given attribute. This is equivalent to the Python expression 'hasattr(self, attr_name)'.

fn getattr<N>(&self, py: Python, attr_name: N) -> PyResult<PyObject> where N: ToPyObject

Retrieves an attribute value. This is equivalent to the Python expression 'self.attr_name'.

fn setattr<N, V>(&self, py: Python, attr_name: N, value: V) -> PyResult<()> where N: ToPyObject, V: ToPyObject

Sets an attribute value. This is equivalent to the Python expression 'self.attr_name = value'.

fn delattr<N>(&self, py: Python, attr_name: N) -> PyResult<()> where N: ToPyObject

Deletes an attribute. This is equivalent to the Python expression 'del self.attr_name'.

fn repr(&self, py: Python) -> PyResult<PyString>

Compute the string representation of self. This is equivalent to the Python expression 'repr(self)'.

fn str(&self, py: Python) -> PyResult<PyString>

Compute the string representation of self. This is equivalent to the Python expression 'str(self)'.

fn is_callable(&self, _py: Python) -> bool

Determines whether this object is callable.

fn call<A>(&self, py: Python, args: A, kwargs: Option<&PyDict>) -> PyResult<PyObject> where A: ToPyObject<ObjectType=PyTuple>

Calls the object. This is equivalent to the Python expression: 'self(*args, **kwargs)'

fn call_method<A>(&self, py: Python, name: &str, args: A, kwargs: Option<&PyDict>) -> PyResult<PyObject> where A: ToPyObject<ObjectType=PyTuple>

Calls a method on the object. This is equivalent to the Python expression: 'self.name(*args, **kwargs)'

fn hash(&self, py: Python) -> PyResult<Py_hash_t>

Retrieves the hash code of the object. This is equivalent to the Python expression: 'hash(self)'

fn is_true(&self, py: Python) -> PyResult<bool>

Returns whether the object is considered to be true. This is equivalent to the Python expression: 'not not self'

fn len(&self, py: Python) -> PyResult<usize>

Returns the length of the sequence or mapping. This is equivalent to the Python expression: 'len(self)'

fn get_item<K>(&self, py: Python, key: K) -> PyResult<PyObject> where K: ToPyObject

This is equivalent to the Python expression: 'self[key]'

fn set_item<K, V>(&self, py: Python, key: K, value: V) -> PyResult<()> where K: ToPyObject, V: ToPyObject

Sets an item value. This is equivalent to the Python expression 'self[key] = value'.

fn del_item<K>(&self, py: Python, key: K) -> PyResult<()> where K: ToPyObject

Deletes an item. This is equivalent to the Python expression 'del self[key]'.

fn iter<'p>(&self, py: Python<'p>) -> PyResult<PyIterator<'p>>

Takes an object and returns an iterator for it. This is typically a new iterator but if the argument is an iterator, this returns itself.
