Struct PtrInner 

pub struct PtrInner<'a, T>
where
    T: ?Sized,
{ /* private fields */ }

The inner pointer stored inside a Ptr.

PtrInner<'a, T> is covariant in 'a and invariant in T.

Implementations

impl<'a, T> PtrInner<'a, T>

where T: 'a + ?Sized,

pub const unsafe fn new(ptr: NonNull<T>) -> PtrInner<'a, T>

Constructs a Ptr from a NonNull.

Safety

The caller promises that:

0. If ptr’s referent is not zero sized, then ptr has valid provenance for its referent, which is entirely contained in some Rust allocation, A.
1. If ptr’s referent is not zero sized, A is guaranteed to live for at least 'a.

pub const fn as_non_null(&self) -> NonNull<T>

Converts this PtrInner<T> to a NonNull<T>.

Note that this method does not consume self. The caller should watch out for unsafe code which uses the returned NonNull in a way that violates the safety invariants of self.

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

Converts this PtrInner<T> to a [*mut T].

Note that this method does not consume self. The caller should watch out for unsafe code which uses the returned *mut T in a way that violates the safety invariants of self.

impl<'a, T> PtrInner<'a, T>

where T: ?Sized,

pub fn project<U, C>(self) -> PtrInner<'a, U>

where C: Project<T, U>, U: ?Sized,

Safety

The caller may assume that the resulting PtrInner addresses the subset of the bytes of self’s referent addressed by C::project(self).

Trait Implementations

impl<'a, T> Clone for PtrInner<'a, T>

where T: 'a + ?Sized,

fn clone(&self) -> PtrInner<'a, T>

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl<'a, T> Copy for PtrInner<'a, T>

where T: 'a + ?Sized,
