Struct SafePtr

Source

pub struct SafePtr<T> { /* private fields */ }

Expand description

Safe pointer wrapper that prevents raw pointer dereference

Implementations§

Source §

impl<T> SafePtr<T>

Source

pub unsafe fn new(ptr: NonNull<T>) -> SafePtr<T>

Create a new safe pointer from a raw pointer

§Safety

The caller must ensure:

The pointer is valid and properly aligned
The memory is initialized for the lifetime of this pointer
No other mutable references exist to this memory

Source

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

Get the raw pointer value for FFI operations

§Safety

The returned pointer should only be used with appropriate safety checks

Source

pub unsafe fn as_mut_ptr(&self) -> *mut T

Get a mutable raw pointer for FFI operations

§Safety

The returned pointer should only be used with appropriate safety checks
