//! This code was AUTOGENERATED using the Codama library.
use carbon_core::{account_utils::next_account, deserialize::ArrangeAccounts};
/// Sets the protocol fee rate for a Whirlpool.
/// Protocol fee rate is represented as a basis point.
/// Only the current fee authority has permission to invoke this instruction.
/// ### Authority
/// - "fee_authority" - Set authority that can modify pool fees in the
///   WhirlpoolConfig
///
/// ### Parameters
/// - `protocol_fee_rate` - The rate that the pool will use to calculate
///   protocol fees going onwards.
///
/// #### Special Errors
/// - `ProtocolFeeRateMaxExceeded` - If the provided default_protocol_fee_rate
///   exceeds MAX_PROTOCOL_FEE_RATE.
