JSON structs JSON conversion utilities for DLC contracts

This module provides functionality to convert Rust-DLC contract types into JSON representations, primarily for console output and API responses. The conversion is currently one-way (to JSON only) as the underlying Rust-DLC types don’t implement Serialize/Deserialize.

Current Usage

• Command line display of contract states
• API responses for contract information
• Debug output and logging

TODO: Future Improvements

• Create proper serializable/deserializable types that mirror Rust-DLC contracts
• Implement bidirectional conversion between JSON and contract types
• Add validation for contract state transitions
• Support custom serialization formats
• Add schema validation for JSON output

Structs

OracleEvent

Represents an oracle event for JSON serialization. Used to track event IDs, oracle public keys, and event types.

Functions

contract_to_value

Main conversion function that handles all contract states. Routes to the appropriate conversion function based on the contract’s state.

offered_contract_to_value

Converts an offered contract to a JSON value with basic contract information. Includes contract ID, party information, collateral, and associated oracle events.

preclosed_contract_to_value

Converts a pre-closed contract to a JSON value, including attestations and signed CET (Contract Execution Transaction) information.

signed_contract_to_value

Converts a signed contract to a JSON value, including funding transaction and contract state information.
