Struct cpython::PySet [−][src]
Represents a Python set
.
Implementations
impl PySet
[src]
pub fn new<I>(py: Python<'_>, iterable: I) -> PyResult<PySet> where
I: ToPyObject,
[src]
I: ToPyObject,
Creates a new set from any iterable
Corresponds to set(iterable)
in Python.
pub fn empty(py: Python<'_>) -> PyResult<PySet>
[src]
Creates an empty set
Corresponds to set()
in Python
pub fn clear(&self, py: Python<'_>) -> PyResult<()>
[src]
Empty an existing set of all values.
pub fn len(&self, _py: Python<'_>) -> usize
[src]
Return the number of items in the set
This is equivalent to Python len(self)
pub fn contains<V>(&self, py: Python<'_>, value: V) -> PyResult<bool> where
V: ToPyObject,
[src]
V: ToPyObject,
Determine if the set contains the specified value.
This is equivalent to the Python expression value in self
.
pub fn add<V>(&self, py: Python<'_>, value: V) -> PyResult<()> where
V: ToPyObject,
[src]
V: ToPyObject,
Add a value.
This is equivalent to the Python expression self.add(value)
.
pub fn discard<V>(&self, py: Python<'_>, value: V) -> PyResult<()> where
V: ToPyObject,
[src]
V: ToPyObject,
Discard a value
This is equivalent to the Python expression self.discard(value)
.
pub fn pop(&self, py: Python<'_>) -> PyResult<PyObject>
[src]
Pop a value
This is equivalent to the Python expression self.pop(value)
.
We get KeyError if the set is empty
