Struct PresentInput

pub struct PresentInput<'a> {
    pub width: usize,
    pub height: usize,
    pub fore_image: &'a mut Vec<u32>,
    pub back_image: &'a mut Vec<u32>,
    pub text_image: &'a mut Vec<u32>,
}

Provides presentation information and contains the arrays that can be mutated to update the window’s contents.

The window’s contents is split into 3 arrays: fore_image, back_image and text_image. The fore_image is an array of u32s containing the colour codes for the foreground colour (or ink colour) of each character on the window. Each u32 represents a single character. Similarly, the back_image contains an array of u32s representing all the background colours (or paper colour) for each character on the window. Finally, text_image contains all the ASCII character codes for each character on the window. This also contains u32s but currently, only the lower 8 bits is considered for rendering. In a future version, higher bits might be used for other effects (such as bold, underline etc).

Fields

width: usize

The current width, in chars, of the application window.

height: usize

The current height, in chars, of the application window.

fore_image: &'a mut Vec<u32>

The array (of size width*height) of u32 values representing the ink colours (or foreground colours) of each character on the window.

back_image: &'a mut Vec<u32>

The array (of size width*height) of u32 values representing the paper colours (or background colours) of each character on the window.

text_image: &'a mut Vec<u32>

The array (of size width*height) of u32 values representing the ASCII character codes of each character on the window. Only the lower 8-bits are currently used.
