Struct TaskReg 

#[repr(C)]
pub struct TaskReg {
    pub priority: u8,
    pub index_in_priority: u8,
    pub _reserved: [u8; 2],
    pub poll_fn: unsafe fn(user_data: *mut (), waker: &Waker) -> Poll<()>,
    pub completed_fn: unsafe fn(user_data: *mut ()) -> bool,
    pub user_data: *mut (),
}

Registration entry placed in the .rivet_tasks linker section. The executor walks these to discover all statically-declared tasks.

Fields

priority: u8

Task priority (0-31).

index_in_priority: u8

Index within this priority level (assigned at init time).

_reserved: [u8; 2]

Reserved padding for alignment.

poll_fn: unsafe fn(user_data: *mut (), waker: &Waker) -> Poll<()>

Poll function. Type-erased: internally casts user_data back to the concrete TaskCell<SIZE> and calls TaskCell::poll::<F>.

completed_fn: unsafe fn(user_data: *mut ()) -> bool

Completed probe. Type-erased: internally casts user_data back to the concrete TaskCell<SIZE> and reports is_completed() — lets the executor skip completed tasks (plan.md [B10]).

user_data: *mut ()

Opaque pointer to the task’s TaskCell. Set at compile time.
