Struct pyo3::GILGuard

#[must_use]
pub struct GILGuard { /* fields omitted */ }

RAII type that represents the Global Interpreter Lock acquisition.

Example

use pyo3::Python;

{
    let gil_guard = Python::acquire_gil();
    let py = gil_guard.python();
} // GIL is released when gil_guard is dropped

Methods

impl GILGuard

If the Python runtime is not already initialized, this function will initialize it. See prepare_freethreaded_python() for details.

pub fn python(&self) -> Python

Retrieves the marker type that proves that the GIL was acquired.
