Sometimes you just need to build an instruction
SwigInstructionBuilder is a fundamental component of the Swig SDK that handles the creation and management of Solana instructions for the Swig protocol.
pub enum AuthorityManager {
Ed25519(Pubkey),
Secp256k1(Box<[u8]>, Box<dyn Fn(&[u8]) -> [u8; 65]>),
Ed25519Session(CreateEd25519SessionAuthority),
Secp256k1Session(CreateSecp256k1SessionAuthority, Box<dyn Fn(&[u8]) -> [u8; 65]>),
}
AuthorityManager enum represents different types of signing authorities supported by the Swig protocol.
