779//! # Ansi Stream
//! Write blazingly fast, free allocation ansi escape codes to a buffer, and flushes them all to any output
//! stream. Supports 8/16 colors, 256 colors, RGB color rendering output.
//!
//! ## ANSI Escape Codes for Terminal Graphics
//! The ANSI escape code standard, formally adopted as ISO/IEC 6429, defines a series of control sequences.
//! Each control sequence begins with a **Control Sequence Introducer** (CSI), defined as a scape character
//! followed immediately by a bracket: **ESC[**. In particular, a CSI followed by a certain number of "parameter bytes"
//! (ASCII 0-9:; <=>?) then the letter m forms a control sequence known as **Select Graphic Rendition** (SGR). If no
//! parameter bytes are explicitly given, then it is assumed to be 0. SGR parameters can be chained together with a semicolon **;**
//! as **delimiter**.
//!
//! Some common SGR parameters are shown below.
//!
//! |Parameter | Effect|
//! |- | -|
//! |0 | reset all SGR effects to their default|
//! |1 | bold or increased intensity|
//! |2 | faint or decreased insensity|
//! |4 | singly underlined|
//! |5 | slow blink|
//! |30-37 | foreground color (3/4 bit)|
//! |38;5;x | foreground color (256 colors, non-standard)|
//! |38;2;r;g;b | foreground color (RGB, non-standard)|
//! |40-47 | background color (8 colors)|
//! |48;5;x | background color (256 colors, non-standard)|
//! |48;2;r;g;b | background color (RGB, non-standard)|
//! |90-97 | bright foreground color (non-standard)|
//! |100-107 | bright background color (non-standard)|
//!
//! ## Examples
//!
//! * Write FC_RED attribute to stream
//!
//! ```
//! use ansistream::{FC_RED, AnsiEscapeStream};
//! use std::io::Cursor;
//!
//! let buffer = Cursor::new(Vec::<u8>::new());
//! let mut astream = AnsiEscapeStream::new(buffer);
//! astream.write_attribute(FC_RED).unwrap();
//! // fcred escape code
//! assert_eq!(&[0x1b, 0x5b, 0x33, 0x31, 0x6d], astream.buffer());
//! ```
//!
//! * Reset an attribute in stream
//!
//! ```
//! use ansistream::{FC_RED, AnsiEscapeStream};
//! use std::io::Cursor;
//!
//! let buffer = Cursor::new(Vec::<u8>::new());
//! let mut astream = AnsiEscapeStream::new(buffer);
//! astream.reset_attribute(FC_RED).unwrap();
//! // fcred escape code
//! assert_eq!(&[0x1b, 0x5b, 0x33, 0x39, 0x6d], astream.buffer());
//! ```
//!
//! * Write formatted foreground green color text to stream.
//!
//! ```
//! use ansistream::{FC_GREEN, AnsiEscapeStream};
//! use std::io::Cursor;
//!
//! let buffer = Cursor::new(Vec::<u8>::new());
//! let mut astream = AnsiEscapeStream::new(buffer);
//! astream
//! .write_text_fc_fmt(FC_GREEN, format_args!("123"))
//! .unwrap();
//! // asserts that fcred was writed and also reseted with fcdefault
//! assert_eq!(
//! &[0x1b, 0x5b, 0x33, 0x32, 0x6d, 0x31, 0x32, 0x33, 0x1b, 0x5b, 0x33, 0x39, 0x6d],
