1.25.0 · sourcepub unsafe fn as_ref<'a>(&self) -> &'a T
pub unsafe fn as_ref<'a>(&self) -> &'a T
Returns a shared reference to the value. If the value may be uninitialized, as_uninit_ref
must be used instead.
For the mutable counterpart see as_mut
.
§Safety
When calling this method, you have to ensure that the pointer is convertible to a reference.
§Examples
use std::ptr::NonNull;
let mut x = 0u32;
let ptr = NonNull::new(&mut x as *mut _).expect("ptr is null!");
let ref_x = unsafe { ptr.as_ref() };
println!("{ref_x}");
