Struct PyFrozenSetBuilder

Source 
pub struct PyFrozenSetBuilder<'py> { /* private fields */ }
Expand description

Allows building a Python frozenset one item at a time

Implementations§

Source§

impl<'py> PyFrozenSetBuilder<'py>

Source

pub fn new(py: Python<'py>) -> PyResult<PyFrozenSetBuilder<'py>>

Create a new FrozenSetBuilder. Since this allocates a PyFrozenSet internally it may panic when running out of memory.

Source

pub fn add<K>(&mut self, key: K) -> PyResult<()>
where K: ToPyObject,

Adds an element to the set.

Source

pub fn finalize_bound(self) -> Bound<'py, PyFrozenSet>

Finish building the set and take ownership of its current value
