Feat Request: Generic `realloc` interface / instruction builder

jacksondoherty commented 2 months ago

Motivation

The only current instruction builder for realloc is specifically tailored to SPL tokens, createReallocateInstruction, which contains parameters like extensionTypes that don't make sense for other use cases. It would be great to have a generic realloc interface / instruction builder similar to SystemProgram.createAccount.

Example use case

  const createAccountIx = createReallocInterfaceInstruction({
    fromPubkey,
    accountPubkey,
    additionalLamports,
    additionalSpace,
    programId,
  });
  // ...send ix

Details

Optionally, instead of "additional" we could have new totals.

No longer convinced this is needed – realloc should probably just be paired with the instruction that intends to use the new space.
