bsv-rs 0.3.4

//! # BSV Transaction
//!
//! Transaction construction, signing, serialization, and SPV verification.
//!
//! This module provides:
//! - Transaction building with inputs and outputs
//! - Input/Output management
//! - Fee calculation and change distribution
//! - Signing with script templates
//! - Serialization (hex, binary, Extended Format)
//! - MerklePath (BRC-74 BUMP) for merkle proofs
//! - BEEF format (BRC-62/95/96) for SPV proofs
//! - Fee models for computing transaction fees
//! - Broadcaster trait for transaction broadcasting
//! - ChainTracker trait for SPV verification
//!
//! # Example
//!
//! ```rust,ignore
//! use bsv_rs::transaction::{Transaction, TransactionInput, TransactionOutput, ChangeDistribution};
//! use bsv_rs::script::LockingScript;
//!
//! // Create a new transaction
//! let mut tx = Transaction::new();
//!
//! // Add an input
//! tx.add_input(TransactionInput::new(
//!     "abc123...".to_string(),
//!     0,
//! ))?;
//!
//! // Add an output
//! tx.add_output(TransactionOutput::new(
//!     100_000,
//!     LockingScript::from_hex("76a914...88ac")?,
//! ))?;
//!
//! // Compute fees and sign
//! tx.fee(None, ChangeDistribution::Equal).await?;
//! tx.sign().await?;
//!
//! // Serialize
//! let hex = tx.to_hex();
//! let txid = tx.id();
//! ```
//!
//! # Fee Models
//!
//! ```rust,ignore
//! use bsv_rs::transaction::{FeeModel, SatoshisPerKilobyte};
//!
//! // 100 satoshis per kilobyte
//! let fee_model = SatoshisPerKilobyte::new(100);
//! let fee = fee_model.compute_fee(&tx)?;
//! ```
//!
//! # BEEF Format
//!
//! ```rust,ignore
//! use bsv_rs::transaction::{Beef, MerklePath};
//!
//! // Parse BEEF from hex
//! let beef = Beef::from_hex("0100beef...")?;
//!
//! // Validate structure
//! assert!(beef.is_valid(false));
//!
//! // Find a transaction
//! if let Some(tx) = beef.find_txid("abc123...") {
//!     println!("Found transaction");
//! }
//! ```
//!
//! # Chain Tracking
//!
//! ```rust,ignore
//! use bsv_rs::transaction::{ChainTracker, MockChainTracker};
//!
//! // Create a mock tracker for testing
//! let mut tracker = MockChainTracker::new(1000);
//! tracker.add_root(999, "merkle_root_hex".to_string());
//!
//! // Verify a merkle root
//! let is_valid = tracker.is_valid_root_for_height("merkle_root_hex", 999)?;
//! ```
