Function arc_ptr_eq

datafusion/expr/src/ptr_eq.rs:26–28

Compares two `Arc` pointers for equality based on their underlying pointers values. This is not equivalent to [`Arc::ptr_eq`] for fat pointers, see that method for more information.

(a: &Arc<T>, b: &Arc<T>)

/// This is not equivalent to [`Arc::ptr_eq`] for fat pointers, see that method
/// for more information.
pub fn arc_ptr_eq<T: ?Sized>(a: &Arc<T>, b: &Arc<T>) -> bool {
    std::ptr::eq(Arc::as_ptr(a), Arc::as_ptr(b))
}

/// Hashes an `Arc` pointer based on its underlying pointer value.
/// The general contract for this function is that if [`arc_ptr_eq`] returns `true`
