Struct pyo3::GILPool

source · [−]

pub struct GILPool { /* private fields */ }

Expand description

A RAII pool which PyO3 uses to store owned Python references.

See the Memory Management chapter of the guide for more information about how PyO3 uses GILPool to manage memory.

Implementations

source

impl GILPool

source

pub unsafe fn new() -> GILPool

Creates a new GILPool. This function should only ever be called with the GIL held.

It is recommended not to use this API directly, but instead to use Python::new_pool, as that guarantees the GIL is held.

Safety

As well as requiring the GIL, see the safety notes on Python::new_pool.

source

pub fn python(&self) -> Python<'_>

Gets the Python token associated with this GILPool.
