Struct Screen 

pub struct Screen { /* private fields */ }

Represents the physical display on the V5 Brain.

Implementations

impl Screen

pub const MAX_VISIBLE_LINES: usize = 12usize

The maximum number of lines that can be visible on the screen at once.

pub const LINE_HEIGHT: i16 = 20i16

The height of a single line of text on the screen.

pub const HORIZONTAL_RESOLUTION: i16 = 480i16

The horizontal resolution of the display.

pub const VERTICAL_RESOLUTION: i16 = 240i16

The vertical resolution of the writable part of the display.

pub unsafe fn new() -> Self

Create a new screen.

Safety

Creating new Screens is inherently unsafe due to the possibility of constructing more than one screen at once allowing multiple mutable references to the same hardware device. Prefer using Peripherals to register devices if possible.

pub fn scroll(&mut self, start: i16, offset: i16) -> Result<(), ScreenError>

Scroll the entire display buffer.

This function effectively y-offsets all pixels drawn to the display buffer by a number (offset) of pixels.

pub fn scroll_area( &mut self, x0: i16, y0: i16, x1: i16, y1: i16, offset: i16, ) -> Result<(), ScreenError>

Scroll a region of the screen.

This will effectively y-offset the display buffer in this area by offset pixels.

pub fn fill( &mut self, shape: &impl Fill<Error = ScreenError>, color: impl IntoRgb, ) -> Result<(), ScreenError>

Draw a filled object to the screen.

pub fn stroke( &mut self, shape: &impl Stroke<Error = ScreenError>, color: impl IntoRgb, ) -> Result<(), ScreenError>

Draw an outlined object to the screen.

pub fn erase(color: impl IntoRgb) -> Result<(), ScreenError>

Wipe the entire display buffer, filling it with a specified color.

pub fn draw_pixel(x: i16, y: i16) -> Result<(), ScreenError>

Draw a color to a specified pixel position on the screen.

pub fn draw_buffer<T, I>( &mut self, x0: i16, y0: i16, x1: i16, y1: i16, buf: T, src_stride: i32, ) -> Result<(), ScreenError>

where T: IntoIterator<Item = I>, I: IntoRgb,

Draw a buffer of pixel colors to a specified region of the screen.

pub fn draw_error(&mut self, msg: &str) -> Result<(), ScreenError>

Draw an error box to the screen.

This function is internally used by the pros-rs panic handler for displaying panic messages graphically before exiting.

pub fn touch_status(&self) -> Result<TouchEvent, ScreenError>

Get the current touch status of the screen.

Trait Implementations

impl Debug for Screen

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl PartialEq for Screen

fn eq(&self, other: &Screen) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl Write for Screen

fn write_str(&mut self, text: &str) -> Result

Writes a string slice into this writer, returning whether the write succeeded.

fn write_char(&mut self, c: char) -> Result<(), Error>

Writes a char into this writer, returning whether the write succeeded.

fn write_fmt(&mut self, args: Arguments<'_>) -> Result<(), Error>

Glue for usage of the write! macro with implementors of this trait.
