//! # Windows Capture Rust Library
//!
//! **Windows Capture** is a highly efficient Rust and Python library that
//! enables you to effortlessly capture the screen using the Graphics Capture
//! API. This library allows you to easily capture the screen of your
//! Windows-based computer and use it for various purposes, such as creating
//! instructional videos, taking screenshots, or recording your gameplay. With
//! its intuitive interface and robust functionality, Windows-Capture is an
//! excellent choice for anyone looking for a reliable and easy-to-use screen
//! capturing solution.
//!
//! ## Features
//!
//! - Only Updates The Frame When Required.
//! - High Performance.
//! - Easy To Use.
//! - Latest Screen Capturing API.
//!
//! ## Installation
//!
//! Add this library to your `Cargo.toml`:
//!
//! ```toml
//! [dependencies]
//! windows-capture = "1.0.65"
//! ```
//! or run this command
//!
//! ```text
//! cargo add windows-capture
//! ```
//!
//! ## Usage
//!
//! ```no_run
//! use std::{
//!     io::{self, Write},
//!     time::Instant,
//! };
//!
//! use windows_capture::{
//!     capture::GraphicsCaptureApiHandler,
//!     encoder::{VideoEncoder, VideoEncoderQuality, VideoEncoderType},
//!     frame::Frame,
//!     graphics_capture_api::InternalCaptureControl,
//!     monitor::Monitor,
//!     settings::{ColorFormat, CursorCaptuerSettings, DrawBorderSettings, Settings},
//! };
//!
//! // This struct will be used to handle the capture events.
//! struct Capture {
//!     // The video encoder that will be used to encode the frames.
//!     encoder: Option<VideoEncoder>,
//!     // To measure the time the capture has been running
//!     start: Instant,
//! }
//!
//! impl GraphicsCaptureApiHandler for Capture {
//!     // The type of flags used to get the values from the settings.
//!     type Flags = String;
//!
//!     // The type of error that can occur during capture, the error will be returned from `CaptureControl` and `start` functions.
//!     type Error = Box<dyn std::error::Error + Send + Sync>;
//!

//!         )?;
//!

//!             encoder: Some(encoder),
//!             start: Instant::now(),
//!         })

//!         self.encoder.as_mut().unwrap().send_frame(frame)?;
//!
//!         // Note: The frame has other uses too for example you can save a single for to a file like this:
//!         // frame.save_as_image("frame.png", ImageFormat::Png)?;
//!         // Or get the raw data like this so you have full control:
//!         // let data = frame.buffer()?;
//!
//!         // Stop the capture after 6 seconds
//!         if self.start.elapsed().as_secs() >= 6 {
//!             // Finish the encoder and save the video.
//!             self.encoder.take().unwrap().finish()?;
//!
//!             capture_control.stop();
//!
//!             // Because there wasn't any new lines in previous prints

//!     // Optional handler called when the capture item (usually a window) closes.
