Struct CreateMint 

pub struct CreateMint {
    pub mint_seed_pubkey: Pubkey,
    pub payer: Pubkey,
    pub address_tree_pubkey: Pubkey,
    pub output_queue: Pubkey,
    pub cpi_context: Option<CpiContext>,
    pub cpi_context_pubkey: Option<Pubkey>,
    pub params: CreateMintParams,
}

Create a mint instruction that creates both a compressed mint AND a Mint Solana account.

Example

use light_token::instruction::{
    CreateMint, CreateMintParams, derive_mint_compressed_address, find_mint_address,
};

// Derive addresses
let compression_address = derive_mint_compressed_address(&mint_seed_pubkey, &address_tree);
let (mint, bump) = find_mint_address(&mint_seed_pubkey);

let params = CreateMintParams {
    decimals: 9,
    address_merkle_tree_root_index, // from rpc.get_validity_proof
    mint_authority,
    proof, // from rpc.get_validity_proof
    compression_address,
    mint,
    bump,
    freeze_authority: None,
    extensions: None,
    rent_payment: 16,  // ~24 hours rent
    write_top_up: 766, // ~3 hours per write
};
let instruction = CreateMint::new(
    params,
    mint_seed_pubkey,
    payer,
    address_tree,
    output_queue,
).instruction()?;

Fields

payer: Pubkey

address_tree_pubkey: Pubkey

output_queue: Pubkey

cpi_context: Option<CpiContext>

cpi_context_pubkey: Option<Pubkey>

params: CreateMintParams
