//! This crate is a port of Tk's Canvas, written using SFML, aiming to provide simple and
//! tkinter-like syntax.
//!
//! # Example:
//!
//! ```no_run
//! use canrust::canvas::{Canvas, Color}; 
//! fn main() {
//!     // Create a canvas:
//!     // size, name, background color
//!     let mut canvas = Canvas::new((800, 600), "Canvas", Color::WHITE);
//!     
//!     // create shapes:
//!     // laser eyes go brrrrr
//!     canvas.create_circle((1., 1.), 20., Color::BLACK, None, None).unwrap();
//!     canvas.create_rectangle((20., 20.), (30., 80.), Color::BLACK, None, None).unwrap();
//!     canvas.create_line((18., 20.), (18., 80), 2., Color::RED, None, None).unwrap();
//!     canvas.create_line((32., 20.), (32. 80.), 2., Color::RED, None, None).unwrap();
//!     
//!     // call the mainloop, objects will keep rendering as long as the program is running
//!     canvas.mainloop()
//! }
//! ```
//! 
//! # Dependencies
//! - SFML 2.5
//! - CSFML 2.5
//!
//! # Installation
//! 
//! Add this to your Cargo.toml file:
//!
//! ```toml
//! [dependencies]
//! canrust = "1.0.0"
//! ```
//! # Examples
//! Full examples can be found in the [`examples`] directory
