Implemented Macros
declare_id!
This functions exactly like the declare_id! macro in the solana_program package. Call it at the top of your program to create a global variable called ID. Note: you must import Pubkey from either solana_program or solana_sdk for this to work.
use declare_id;
use Pubkey;
declare_id!;
declare_pda!
This macro takes in a base58-encoded PDA, a base-58 encoded program id, and a string literal representing the seed of the PDA. The macro will check that the supplied PDA is indeed the output of calling find_program_address on the program id and seed. If this succeeds, then the bump seed will be written to a variable called BUMP and the PDA will be written to a variable called ID. Note: you must import Pubkey from either solana_program or solana_sdk for this to work.
use declare_pda;
use Pubkey;
declare_pda!;
