Struct FFINonNull 

pub struct FFINonNull<T>(/* private fields */)
where
    T: ?Sized;

Represents a non-null raw pointer, similar to core::ptr::NonNull, but it instead doesn’t guarantee that the pointer is valid, instead IT SHOULD BE valid, additional checks should be performed before using it.

The purpose is for use alongside crate::ffi::option::OptZero.

Implementations

impl<T> FFINonNull<T>

where T: ?Sized,

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

Creates a new instance of FFINonNull if the pointer is not null otherwise returns None.

pub const unsafe fn new_unchecked(ptr: *mut T) -> FFINonNull<T>

Creates a new instance of FFINonNull without checking if the pointer is null.

Safety

The caller must ensure that the pointer is not null.

pub const fn as_ptr(&self) -> *mut T

Returns the raw pointer stored in this FFINonNull instance.

Trait Implementations

impl<T> Clone for FFINonNull<T>

where T: Clone + ?Sized,

fn clone(&self) -> FFINonNull<T>

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl<T> Debug for FFINonNull<T>

where T: Debug + ?Sized,

fn fmt(&self, f: &mut Formatter<'_>) -> Result<(), Error>

Formats the value using the given formatter.

impl<T> NotZeroable for FFINonNull<T>

where T: ?Sized,

fn is_zero(&self) -> bool

impl<T> Ord for FFINonNull<T>

where T: Ord + ?Sized,

fn cmp(&self, other: &FFINonNull<T>) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Self

where Self: Sized,

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Self

where Self: Sized,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Self

where Self: Sized,

Restrict a value to a certain interval.

impl<T> PartialEq for FFINonNull<T>

where T: PartialEq + ?Sized,

fn eq(&self, other: &FFINonNull<T>) -> bool
