//! This code was AUTOGENERATED using the Codama library.

/// Initializes a fee_tier account usable by Whirlpools in a WhirlpoolConfig
/// space. ### Authority
/// - "fee_authority" - Set authority in the WhirlpoolConfig
///
/// ### Parameters
/// - `tick_spacing` - The tick-spacing that this fee-tier suggests the
///   default_fee_rate for.
/// - `default_fee_rate` - The default fee rate that a pool will use if the pool
///   uses this
///
/// fee tier during initialization.
/// #### Special Errors
/// - `InvalidTickSpacing` - If the provided tick_spacing is 0.
/// - `FeeRateMaxExceeded` - If the provided default_fee_rate exceeds
///   MAX_FEE_RATE.
