9/// Declare a program module from an Anchor IDL JSON file.
10///
11/// Looks for `idls/{name}.json` by walking up from `CARGO_MANIFEST_DIR`.
12///
13/// # Example
14/// ```ignore
15/// anchor_parser::declare_program!(my_program);
16/// ```
17///
18/// This generates a module `my_program` containing:
19/// - `ID` constant (`Pubkey`)
20/// - `types` module (struct/enum/alias definitions)
21/// - `accounts` module (account types with discriminators + fetch)
22/// - `events` module (event types with `from_log`)
23/// - `instructions` module (instruction builders → `Instruction`)
24/// - `constants` module
