Struct ScreenSplitMux

pub struct ScreenSplitMux<'a, S: Screen<'a>> { /* private fields */ }

Split-screen manager that multiplexes for multiple splits.

This enables two users (e.g., the kernel and all userspace apps) to share a single physical screen. Each split screen is assigned a fixed region.

Implementations

impl<'a, S: Screen<'a>> ScreenSplitMux<'a, S>

pub fn new(screen: &'a S) -> Self

Trait Implementations

impl<'a, S: Screen<'a>> DeferredCallClient for ScreenSplitMux<'a, S>

fn handle_deferred_call(&self)

Software interrupt function that is called when the deferred call is triggered.

fn register(&'static self)

impl<'a, S: Screen<'a>> ScreenClient for ScreenSplitMux<'a, S>

fn command_complete(&self, _r: Result<(), ErrorCode>)

The screen will call this function to notify that a command (except write) has finished.

fn write_complete( &self, data: SubSliceMut<'static, u8>, r: Result<(), ErrorCode>, )

The screen will call this function to notify that the write command has finished. This is different from command_complete as it has to pass back the write buffer

fn screen_is_ready(&self)

Some screens need some time to start, this function is called when the screen is ready.
