Struct pyo3::buffer::ReadOnlyCell

source ·

#[repr(transparent)]
pub struct ReadOnlyCell<T: Element>(_);

Available on non-Py_LIMITED_API or Py_3_11 only.

Expand description

Like std::cell::Cell, but only provides read-only access to the data.

&ReadOnlyCell<T> is basically a safe version of *const T: The data cannot be modified through the reference, but other references may be modifying the data.

impl<T: Element> ReadOnlyCell<T>

source

pub fn get(&self) -> T
