Struct CreateMintsCpi 

pub struct CreateMintsCpi<'a, 'info> {
    pub mint_seed_accounts: &'a [AccountInfo<'info>],
    pub payer: AccountInfo<'info>,
    pub address_tree: AccountInfo<'info>,
    pub output_queue: AccountInfo<'info>,
    pub state_merkle_tree: AccountInfo<'info>,
    pub compressible_config: AccountInfo<'info>,
    pub mints: &'a [AccountInfo<'info>],
    pub rent_sponsor: AccountInfo<'info>,
    pub system_accounts: SystemAccountInfos<'info>,
    pub cpi_context_account: AccountInfo<'info>,
    pub params: CreateMintsParams<'a>,
}

CPI struct for on-chain programs to create multiple mints.

Uses named account fields for clarity and safety - no manual index calculations.

Example

use light_token::instruction::{CreateMintsCpi, CreateMintsParams, SingleMintParams, SystemAccountInfos};

let params = CreateMintsParams::new(vec![mint_params_1, mint_params_2], proof);

CreateMintsCpi {
    mint_seeds: vec![mint_signer1.clone(), mint_signer2.clone()],
    payer: payer.clone(),
    address_tree: address_tree.clone(),
    output_queue: output_queue.clone(),
    compressible_config: config.clone(),
    mints: vec![mint_pda1.clone(), mint_pda2.clone()],
    rent_sponsor: rent_sponsor.clone(),
    system_accounts: SystemAccountInfos { ... },
    cpi_context_account: cpi_context.clone(),
    params,
}.invoke()?;

Fields

mint_seed_accounts: &'a [AccountInfo<'info>]

Mint seed accounts (signers) - one per mint

payer: AccountInfo<'info>

Fee payer (also used as authority)

address_tree: AccountInfo<'info>

Address tree for new mint addresses

output_queue: AccountInfo<'info>

Output queue for compressed accounts

state_merkle_tree: AccountInfo<'info>

State merkle tree (required for decompress discriminator validation)

compressible_config: AccountInfo<'info>

CompressibleConfig account

mints: &'a [AccountInfo<'info>]

Mint PDA accounts (writable) - one per mint

rent_sponsor: AccountInfo<'info>

Rent sponsor PDA

system_accounts: SystemAccountInfos<'info>

Standard Light Protocol system accounts

cpi_context_account: AccountInfo<'info>

CPI context account

params: CreateMintsParams<'a>

Parameters

Implementations

impl<'a, 'info> CreateMintsCpi<'a, 'info>

pub fn validate(&self) -> Result<(), ProgramError>

Validate that the struct is properly constructed.

pub fn invoke(self) -> Result<(), ProgramError>

Execute all CPIs to create and decompress all mints.

Signer seeds are extracted from SingleMintParams::mint_signer_seeds and SingleMintParams::authority_seeds for each CPI call (0, 1, or 2 seeds per call).
