Struct CreateBuffers 

pub struct CreateBuffers<'a> {
    pub program_id: Pubkey,
    pub payer: Pubkey,
    pub buffers: &'a [(Pubkey, Pubkey)],
}

Builder for a CreateBuffer instruction that creates one buffer per (buffer_pda, mint) pair in buffers.

Each buffer_pda must be the canonical PDA returned by crate::pda::buffer::find_buffer_pda for its mint; the program derives the bump itself and rejects any other address. payer funds every new token account’s rent.

Buffer creation is idempotent: an already-existing buffer_pda is left unchanged and the instruction still succeeds, so two parties racing to create the same buffer both succeed.

Wire format: [discriminator=4], 1 byte. The tokens are implied by the mint accounts, so no further data is needed. Required accounts: [payer (W,S), system_program (R), token_program (R), (buffer_pda (W), mint (R))...]. The three shared accounts come first and are read positionally; the per-buffer pairs follow. The system program only has to be present so the CreateAccount CPI can dispatch; it isn’t read by index.

Fields

program_id: Pubkey

payer: Pubkey

buffers: &'a [(Pubkey, Pubkey)]
