Struct crndm::ptr::NonNull

pub struct NonNull<T: PSafe + ?Sized> { /* fields omitted */ }

An unsafe pointer with dereferencing capability

This type is !PSafe and its constructor functions are unsafe. This is because of NonNull treating like a raw pointer. NonNull objects are useful for obtaining performance.

PNonNull is an alias name in the pool module for LogNonNull.

Implementations

impl<T: PSafe> NonNull<T>

pub const fn new_unchecked(ptr: *const T) -> Self

Creates a new NonNull.

Safety

ptr and logged must be non-null.

pub fn new(ptr: *const T) -> Option<Self>

Creates a Some(NonNull) if ptr is not null; otherwise None.

pub fn as_ref<'a, 'b>(&'a self) -> &'b T
