Trait datafusion::common::utils::DataPtr

pub trait DataPtr {
    // Required method
    fn data_ptr(this: &Self) -> *const ();

    // Provided method
    fn data_ptr_eq(this: &Self, other: &Self) -> bool { ... }
}

An extension trait for smart pointers. Provides an interface to get a raw pointer to the data (with metadata stripped away).

This is useful to see if two smart pointers point to the same allocation.

Required Methods

fn data_ptr(this: &Self) -> *const ()

Returns a raw pointer to the data, stripping away all metadata.

Provided Methods

fn data_ptr_eq(this: &Self, other: &Self) -> bool

Check if two pointers point to the same data.

Object Safety

This trait is not object safe.
