#[repr(transparent)]
pub struct Register(_);

The element of the Doorbell Array.

Implementations

impl Register

pub unsafe fn new<M1, M2>( mmio_base: usize, capability: &Capability<M2>, mapper: M1 ) -> ReadWrite<Self, M1>where M1: Mapper, M2: Mapper + Clone,

Creates a new accessor to the Doorbell Array.

Safety

Caller must ensure that the only one accessor is created, otherwise it may cause undefined behavior such as data race.

This method panics if the base address of the Doorbell Array is not aligned correctly.
