Struct UniquePtr 

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

A wrapper around a raw pointer that enforces single ownership.

When UniquePtr<T> is dropped, it frees the underlying object using the provided DropFn.

Safety

This is an internal helper for the ABI membrane. It should not be exposed to external callers.

Implementations

impl<T> UniquePtr<T>

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

Create a new UniquePtr from a raw pointer.

Safety

• ptr must be a valid, uniquely-owned pointer or NULL.
• drop_fn must correctly free the pointed-to object.
• No other code may hold a reference to this pointer.

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

Get a raw pointer (for FFI calls). The caller must not free the pointer.

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

Get a mutable raw pointer (for FFI calls that mutate). The caller must not free the pointer.

pub fn into_raw(self) -> *mut T

Release ownership and return the raw pointer. The caller is now responsible for freeing it.

Trait Implementations

impl<T> Drop for UniquePtr<T>

fn drop(&mut self)

Executes the destructor for this type.

fn pin_drop(self: Pin<&mut Self>)

🔬This is a nightly-only experimental API. (pin_ergonomics)

Execute the destructor for this type, but different to Drop::drop, it requires self to be pinned.
