Modules

An Anchor generated module, providing a set of structs mirroring the structs deriving Accounts, where each field is a Pubkey. This is useful for specifying accounts for a client.
An Anchor generated module containing the program’s set of instructions, where each method handler in the #[program] mod is associated with a struct defining the input arguments to the method. These should be used directly, when one wants to serialize Anchor instruction data, for example, when speciying instructions on a client.

Confirms that a given pubkey is equivalent to the program ID
The Anchor codegen exposes a programming model where a user defines a set of methods inside of a #[program] module in a way similar to writing RPC request handlers. The macro then generates a bunch of code wrapping these user defined methods into something that can be executed on Solana.
