Trait PtrWrapper 

Source 
pub trait PtrWrapper: Sized {
    type Pointer;

    // Required methods
    unsafe fn from_raw(raw: *mut Self::Pointer) -> Self;
    fn as_ptr(&self) -> *const Self::Pointer;

    // Provided methods
    fn into_raw(self) -> *mut Self::Pointer { ... }
    fn as_ptr_mut(&mut self) -> *mut Self::Pointer { ... }
}

Required Associated Types§

Source

type Pointer

Required Methods§

Source

unsafe fn from_raw(raw: *mut Self::Pointer) -> Self

Wraps the pointer into a owned wrapper.

§Safety

Pointer must be valid.

Source

fn as_ptr(&self) -> *const Self::Pointer

Returns the inner pointer.

Provided Methods§

Source

fn into_raw(self) -> *mut Self::Pointer

Consumes the wrapper and transfers ownershop to the pointer

This does NOT drop the wrapper internally.

Source

fn as_ptr_mut(&mut self) -> *mut Self::Pointer

Returns the inner pointer (mutable version).

Dyn Compatibility§

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety".
