Struct wasmer_experimental_io_devices_lib::framebuffer::FrameBufferCtx

pub struct FrameBufferCtx { /* fields omitted */ }

Wrapper around framebuffer primitives, allows you to draw and get input easily

Methods

impl FrameBufferCtx

pub fn new(x: u32, y: u32) -> Result<Self, String>

Create a new framebuffer with the specified resolution.

pub fn get_input(&mut self) -> Option<InputIter>

Gets the input from the input file and returns an iterator that parses the results

pub fn set_resolution(&mut self, x: u32, y: u32) -> Option<()>

resize the window

pub fn draw(&mut self) -> Option<()>

Draws the values in the buffer to the screen

pub fn update_pixels<I>(&mut self, x: u32, y: u32, pixels: I) -> Option<u32> where
    I: Iterator<Item = RGBA>, 

Updates the buffer starting at position (x,y) with the specified colors If the length of pixels + x is greater than the max length of the row, drawing will continue at (0, y + 1) and so on.

Returns None if something went wrong, otherwise returns the numbers of pixels written to the buffer.

To be able to see these updates, you must call draw
