Trait RefCounted

pub unsafe trait RefCounted:
    Sized
    + Clone
    + 'static {
    type InnerType;

    // Required methods
    unsafe fn ref_(this: *const Self::InnerType) -> *const Self::InnerType;
    fn as_ptr(&self) -> *const Self::InnerType;
    unsafe fn into_raw(self) -> *const Self::InnerType;
    unsafe fn from_raw(this: *const Self::InnerType) -> Self;
}

Required Associated Types

type InnerType

The inner type

Required Methods

unsafe fn ref_(this: *const Self::InnerType) -> *const Self::InnerType

The function used to increment the inner type refcount

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

Provides access to a raw pointer to InnerType

unsafe fn into_raw(self) -> *const Self::InnerType

Converts the RefCounted object to a raw pointer to InnerType

unsafe fn from_raw(this: *const Self::InnerType) -> Self

Converts a raw pointer to InnerType to a RefCounted object

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
