Rust Raw Pointers Creating and using constant raw pointers
Example
// Let's take an arbitrary piece of data, a 4-byte integer in this case
let some_data: u32 = 14;
// Create a constant raw pointer pointing to the data above
let data_ptr: *const u32 = &some_data as *const u32;
// Note: creating a raw pointer is totally safe but dereferencing a raw pointer requires an
// unsafe block
unsafe {
let deref_data: u32 = *data_ptr;
println!("Dereferenced data: {}", deref_data);
}
The above code will output:
Dereferenced data: 14
