Struct EdgeSnake 

pub struct EdgeSnake {
    pub x: u16,
    pub y: u16,
    last_update: Instant,
    frame_duration: Duration,
}

Manages the welcome-screen snake moving across the top row.

Fields

x: u16

Current horizontal position of the head.

y: u16

Kept at the top row; exposed for compatibility with the menu renderer.

last_update: Instant

Last update timestamp for frame rate control.

frame_duration: Duration

Target duration between animation frames (speed).

Implementations

impl EdgeSnake

pub fn new() -> Self

Creates a new EdgeSnake instance.

pub fn update(&mut self, area: &Rect)

Moves the snake one cell to the right on the top row, wrapping at the opposite edge.

pub fn render(&self, frame: &mut Frame<'_>, area: &Rect)

fn next_x(x: u16, width: u16) -> u16

Returns the next head position, wrapping from the right edge to the left edge.

pub fn get_positions(&self, width: u16) -> Vec<(u16, u16)>

Returns the top-row coordinates for the head and its body segments. Body segments wrap horizontally as well, so the animation remains continuous at the edge.

Trait Implementations

impl Default for EdgeSnake

fn default() -> Self

Returns the “default value” for a type.
