//! # SansIO Codec - Protocol Codecs for SansIO
//!
//! `sansio-codec` provides reusable codec implementations for the sansio ecosystem,
//! including frame decoders, string codecs, and transport abstractions.
//!
//! ## Features
//!
//! - **Frame Decoders**: Line-based frame decoders for parsing delimited streams
//! - **String Codecs**: UTF-8 string encoding/decoding
//! - **Transport Abstractions**: Tagged message types with transport metadata
//! - **Sans-IO Design**: Pure protocol logic without I/O dependencies
//!
//! ## Quick Start
//!
//! ```toml
//! [dependencies]
//! sansio-codec = "0.0.8"
//! ```
//!
//! ## Building a Pipeline with Codecs
//!
//! ```rust,no_run
//! use sansio::Pipeline;
//! use sansio_codec::{
//!     LineBasedFrameDecoder, TaggedByteToMessageCodec, TaggedStringCodec, TerminatorType,
//! };
//! use sansio_transport::{TaggedBytesMut, TaggedString};
//! use std::rc::Rc;
//!
//! let pipeline = Rc::new(Pipeline::<TaggedBytesMut, TaggedString>::new());
//!
//! // Add line-based frame decoder
//! let frame_decoder = TaggedByteToMessageCodec::new(Box::new(
//!     LineBasedFrameDecoder::new(8192, true, TerminatorType::BOTH)
//! ));
//! pipeline.add_back(frame_decoder);
//!
//! // Add string codec
//! pipeline.add_back(TaggedStringCodec::new());
//!
//! // Add your business logic handler
//! // pipeline.add_back(your_handler);
//!
//! pipeline.update();
//! ```
//!
//! ## Modules
//!
//! - [`byte_to_message_decoder`]: Frame decoders for parsing byte streams
//! - [`string_codec`]: UTF-8 string encoding/decoding handlers
//!
//! ## Transport Context
//!
//! The transport module provides tagged message types that carry metadata:
//!
//! ```rust
//! use sansio_transport::{TransportContext, TaggedBytesMut, TransportProtocol};
//! use std::time::Instant;
//! use bytes::BytesMut;
//!
//! let msg = TaggedBytesMut {
//!     now: Instant::now(),
//!     transport: TransportContext {
//!         local_addr: "127.0.0.1:8080".parse().unwrap(),
//!         peer_addr: "127.0.0.1:1234".parse().unwrap(),
//!         transport_protocol: TransportProtocol::TCP,
//!         ecn: None,
//!     },
//!     message: BytesMut::from("Hello"),
//! };
//! ```
