Foreign Type core::alloc::Opaque

extern {
    pub type Opaque;
}

🔬 This is a nightly-only experimental API. (allocator_api #32838)

the precise API and guarantees it provides may be tweaked slightly, especially to possibly take into account the types being stored to make room for a future tracing garbage collector

An opaque, unsized type. Used for pointers to allocated memory.

This type can only be used behind a pointer like *mut Opaque or ptr::NonNull<Opaque>. Such pointers are similar to C’s void* type.

Similar to std::ptr::null, which requires T: Sized.
