Trait ForeignTypeRef

pub trait ForeignTypeRef: Sized {
    type CType;

    // Provided methods
    unsafe fn from_ptr<'a>(ptr: *mut Self::CType) -> &'a Self { ... }
    unsafe fn from_ptr_mut<'a>(ptr: *mut Self::CType) -> &'a mut Self { ... }
    fn as_ptr(&self) -> *mut Self::CType { ... }
}

A trait implemented by types which reference borrowed foreign types.

Required Associated Types

type CType

The raw C type.

Provided Methods

unsafe fn from_ptr<'a>(ptr: *mut Self::CType) -> &'a Self

Constructs a shared instance of this type from its raw type.

unsafe fn from_ptr_mut<'a>(ptr: *mut Self::CType) -> &'a mut Self

Constructs a mutable reference of this type from its raw type.

fn as_ptr(&self) -> *mut Self::CType

Returns a raw pointer to the wrapped value.

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.
