Struct TypedPtrUninit

pub struct TypedPtrUninit<'mem, T>(/* private fields */);

A pointer to an uninitialized value with a lifetime.

Implementations

impl<'mem, T> TypedPtrUninit<'mem, T>

pub fn new(ptr: *mut T) -> Self

Create a new opaque pointer from a mutable pointer

This is safe because it’s generic over T

pub unsafe fn put(self, value: T) -> &'mem mut T

Write a value to this location and convert to an initialized pointer

Safety

The pointer must be properly aligned for T and point to allocated memory that can be safely written to.

pub unsafe fn assume_init(self) -> &'mem mut T

Assumes the pointer is initialized and returns an Opaque pointer

Safety

The pointer must actually be pointing to initialized memory of the correct type.

pub unsafe fn field_uninit_at<U>( &mut self, offset: usize, ) -> TypedPtrUninit<'mem, U>

Returns a pointer with the given offset added

Safety

Offset is within the bounds of the allocated memory and U is the correct type for the field.
