Trait Implementations

impl<const SCREEN_BUF_LEN: usize, CAP: MemoryAllocationCapability + 'static> Component for ScreenComponent<SCREEN_BUF_LEN, CAP>

type StaticInput = (&'static mut MaybeUninit<[u8; SCREEN_BUF_LEN]>, &'static mut MaybeUninit<Screen<'static>>)

An optional type to specify the chip or board specific static memory that a component needs to setup the output object(s). This is the memory that [crate::static_buf!()] would normally setup, but generic components cannot setup static buffers for types which are chip-dependent, so those buffers have to be passed in manually, and the [Component::StaticInput] type makes this possible.

type Output = &'static Screen<'static>

The type (e.g., capsule, peripheral) that this implementation of [Component] produces via [Component::finalize()]. This is typically a static reference (&'static).

fn finalize(self, static_input: Self::StaticInput) -> Self::Output

A factory method that returns an instance of the Output type of this [Component] implementation. This is used in the boot sequence to instantiate and initialize part of the Tock kernel. This factory method may only be called once per Component instance.
