Struct kernel::task::TaskRef

source · [−]

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

Expand description

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.

Methods from Deref<Target = Task>
