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
rust
use ellipsis_macros::declare_id;
declare_id!("9BoN4yBYwH63LFM9fDamaHK62YjM56hWYZqok7MnAakJ");
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
rust
use ellipsis_macros::declare_pda;
declare_id!(
"F46iAvcTENE8BBpSaQnumRw868p9o37AFhFvBkfKqu1e",
"9BoN4yBYwH63LFM9fDamaHK62YjM56hWYZqok7MnAakJ",
"hello"
