Allow callers to pass custom IDL JSON strings for any program with optional override of built-in IDLs. Returns SHA256 hash of compressed IDL and source tracking (built-in vs custom) for verification. Key changes: - Add optional custom_idls parameter to parse_transaction() - Add ProgramType enum for 13 built-in IDL types - Add IdlSource and idl_hash fields to SolanaParsedInstructionData - Add compute_idl_hash() for IDL verification - Update CLI to accept --custom-idl flag with optional --override - Maintain backward compatibility (existing calls add , None)
- Add embedded_idls.rs with include_str!() for all 13 IDL files - Add ProgramType::all() and ProgramType::idl_json() methods - Create CustomIdl enum (Parsed/Json) and CustomIdlConfig struct - Add parse_transaction_with_idls() as new preferred API - Update IdlRecord to use program_type instead of file_path - Eliminate runtime file system access for built-in IDLs This fixes the bug where IDL lookups failed when running from directories other than the project root.
Add a new public function that allows parsing individual Solana instruction data using a provided IDL, without requiring full transaction context. This enables parsing instruction data in isolation when only the raw bytes and IDL are available. Co-Authored-By: Claude Opus 4.5 <noreply@anthropic.com>
