Struct melpomene::sim_drivers::emb_display::CommanderTask

struct CommanderTask {
    kernel: &'static Kernel,
    cmd: RequestStream<EmbDisplayService>,
    width: u32,
    height: u32,
}

This task is spawned by the call to SimDisplay::register. It is a single async function that will process requests, and periodically redraw the framebuffer.

Fields

kernel: &'static Kernel

cmd: RequestStream<EmbDisplayService>

width: u32

height: u32

Implementations

impl CommanderTask

async fn run(self, width: u32, height: u32, settings: DisplayConfig)

The entrypoint for the driver execution

async fn message_loop(&self, mutex: Arc<Mutex<Option<Context>>>)

This loop services incoming client requests.

Generally, don’t handle errors when replying to clients, this indicates that they sent us a message and “hung up” without waiting for a response.

async fn draw_mono( &self, fc: &MonoChunk, mutex: &Mutex<Option<Context>>, ) -> Result<(), ()>

Draw the given MonoChunk to the persistent framebuffer
