Macro declare_program 

declare_program!() { /* proc-macro */ }

Generate a complete program module from an Anchor IDL JSON file.

Searches for idls/{name}.json by walking up from CARGO_MANIFEST_DIR.

Generated items

• ID — the program’s Pubkey
• types — shared structs, enums, and type aliases
• accounts — account structs with discriminator and deserialization
• events — event structs with from_logs / from_cpi_logs parsers
• instructions — builder functions → Result<Instruction, io::Error>
• constants — program constants
• utils — Event / Account wrapper enums

Example

anchor_parser::declare_program!(my_program);

// Use generated types:
use my_program::accounts::MyAccount;
use my_program::events::MyEvent;
use my_program::instructions;
