Macro indexer_id 

macro_rules! indexer_id {
    () => { ... };
    ($value:tt) => { ... };
}

Converts a sequence of string literals containing hex-encoded data into a new IndexerId at compile time.

To create an IndexerId from a string literal (no 0x prefix) at compile time:

const INDEXER_ID: IndexerId = indexer_id!("0002c67268fb8c8917f36f865a0cbdf5292fa68d");

If no argument is provided, the macro will create an IndexerId with the zero address:

const INDEXER_ID: IndexerId = indexer_id!();

assert_eq!(INDEXER_ID, Address::ZERO);
