Struct kernel::task::TaskRef

pub struct TaskRef<'a> { /* private fields */ }

A wrapper for a shared reference to Task that isn’t Send.

We make this explicitly not Send so that we can use it to represent the current thread without having to increment/decrement the task’s reference count.

Invariants

The wrapped Task remains valid for the lifetime of the object.
