Trait intrusive_collections::IntrusivePointer
[−]
[src]
pub unsafe trait IntrusivePointer<T: ?Sized> { fn into_raw(self) -> *const T; unsafe fn from_raw(ptr: *const T) -> Self; }
Trait representing an owned pointer type which can be converted to and from a raw pointer.
This trait is automatically implemented for the standard Box, Rc and
Arc types. It is also implemented for the UnsafeRef pointer type
provided by this crate.
Rust reference types (&T) also implement IntrusivePointer. This is safe
because the lifetime of an intrusive collection is limited to that of the
pointer type. This means that a collection of &'a T cannot outlive any
objects that are inserted into the collection.
Required Methods
fn into_raw(self) -> *const T
Consumes the owned pointer and returns a raw pointer to the owned object.
unsafe fn from_raw(ptr: *const T) -> Self
Constructs an owned pointer from a raw pointer which was previously
returned by into_raw.
