//! Instruction for creating new tokens with bonding curves
//!
//! This module provides the functionality to create new tokens with associated bonding curves.
//! It includes the instruction data structure and helper function to build the Solana instruction.

///
/// # Fields
///
/// * `name` - Name of the token to be created
/// * `symbol` - Symbol/ticker of the token to be created
/// * `uri` - Metadata URI containing token information (image, description, etc.)
/// * `creator` - Public key of the token creator

/// Creates an instruction to create a new token with bonding curve
///
/// Creates a new SPL token with an associated bonding curve that determines its price.
/// The token will have metadata and be tradable according to the bonding curve formula.
///
/// # Arguments
///
/// * `payer` - Keypair that will pay for account creation and transaction fees
/// * `mint` - Keypair for the new token mint account that will be created
/// * `args` - Create instruction data containing token name, symbol, metadata URI, and creator
///
/// # Returns
///
/// Returns a Solana instruction that when executed will create the token and its accounts
///
/// # Account Requirements
///
/// The instruction requires the following accounts in this order:
/// 1. Mint account (signer, writable)
/// 2. Mint authority PDA (readonly)
/// 3. Bonding curve PDA (writable)
/// 4. Bonding curve token account (writable)
/// 5. Global configuration PDA (readonly)
/// 6. MPL Token Metadata program (readonly)
/// 7. Metadata PDA (writable)
/// 8. Payer account (signer, writable)
/// 9. System program (readonly)
/// 10. Token program (readonly)
/// 11. Associated token program (readonly)
/// 12. Rent sysvar (readonly)
/// 13. Event authority (readonly)
/// 14. Pump.fun program ID (readonly)
