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

/// Add liquidity to a position in the Whirlpool. This call also updates the
/// position's accrued fees and rewards. ### Authority
/// - `position_authority` - authority that owns the token corresponding to this
///   desired position.
///
/// ### Parameters
/// - `liquidity_amount` - The total amount of Liquidity the user is willing to
///   deposit.
/// - `token_max_a` - The maximum amount of tokenA the user is willing to
///   deposit.
/// - `token_max_b` - The maximum amount of tokenB the user is willing to
///   deposit.
///
/// #### Special Errors
/// - `LiquidityZero` - Provided liquidity amount is zero.
/// - `LiquidityTooHigh` - Provided liquidity exceeds u128::max.
/// - `TokenMaxExceeded` - The required token to perform this operation exceeds
///   the user defined amount.
