Struct ScreenSplitUser

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

An implementation of Screen for a subregion of the actual screen.

Implementations

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

pub fn new( mux: &'a ScreenSplitMux<'a, S>, x: usize, y: usize, width: usize, height: usize, ) -> Self

pub fn add_to_mux(&'a self)

Trait Implementations

impl<'a, S: Screen<'a>> ListNode<'a, ScreenSplitUser<'a, S>> for ScreenSplitUser<'a, S>

fn next(&'a self) -> &'a ListLink<'a, ScreenSplitUser<'a, S>>

impl<'a, S: Screen<'a>> Screen<'a> for ScreenSplitUser<'a, S>

fn set_client(&self, client: &'a dyn ScreenClient)

Set the object to receive the asynchronous command callbacks.

fn get_resolution(&self) -> (usize, usize)

Get a tuple (width, height) with the current resolution (in pixels).

fn get_pixel_format(&self) -> ScreenPixelFormat

Get the current pixel format.

fn get_rotation(&self) -> ScreenRotation

Get the current rotation.

fn set_write_frame( &self, x: usize, y: usize, width: usize, height: usize, ) -> Result<(), ErrorCode>

Sets the write frame.

fn write( &self, buffer: SubSliceMut<'static, u8>, continue_write: bool, ) -> Result<(), ErrorCode>

Write data from buffer to the selected write frame.

fn set_brightness(&self, _brightness: u16) -> Result<(), ErrorCode>

Set the display brightness value.

fn set_power(&self, _enabled: bool) -> Result<(), ErrorCode>

Controls the screen power supply.

fn set_invert(&self, _enabled: bool) -> Result<(), ErrorCode>

Controls the color inversion mode.

impl<'a, S: Screen<'a>> ScreenClient for ScreenSplitUser<'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.
