Features

plane

Enable this to make andiskaz's Vec2 be an alias for the crate gardiz's Vec2. Otherwise, andiskaz's Vec2 is a new struct.

Example Snake Game

See this folder.

lib.rs:

This crate provides basic utilities for writing applications with Terminal User Interface (TUI). It provides an event listener, and it provides a handle to a double buffered screen renderer.

Examples

This is an example for a simple Hello, World! application. For more examples, see examples folder.
