Struct kvarn_utils::SuperUnsafePointer

source · [−]

#[repr(transparent)]
pub struct SuperUnsafePointer<T> { /* private fields */ }

Expand description

Should only be used from within Kvarn! A super-unsafe pointer. Must be used with great care.

Safety

The safety of this struct requires you to

make sure the lifetime of the reference lives longer than all references returned by Self::get and Self::get_mut.
make sure no other references exist. You can use Self::new_mut to garantuee this.

This type implements Send + Sync to allow it to cross async boundarys. This type is used in the move || part of extensions.
