[−][src]Struct pyo3::types::PyFrozenSet
Represents a Python frozenset
Methods
impl PyFrozenSet
[src]
pub fn new<'p, T: ToPyObject>(
py: Python<'p>,
elements: &[T]
) -> PyResult<&'p PyFrozenSet>
[src]
py: Python<'p>,
elements: &[T]
) -> PyResult<&'p PyFrozenSet>
Creates a new frozenset.
May panic when running out of memory.
pub fn empty<'p>(py: Python<'p>) -> PyResult<&'p PySet>
[src]
Creates a new empty frozen set
pub fn len(&self) -> usize
[src]
Return the number of items in the set. This is equivalent to len(p) on a set.
pub fn is_empty(&self) -> bool
[src]
Check if set is empty.
pub fn contains<K>(&self, key: K) -> PyResult<bool> where
K: ToBorrowedObject,
[src]
K: ToBorrowedObject,
Determine if the set contains the specified key.
This is equivalent to the Python expression key in self
.
