//! This code was AUTOGENERATED using the Codama library.
use carbon_core::{account_utils::next_account, deserialize::ArrangeAccounts};
/// Open a bundled position in a Whirlpool. No new tokens are issued
/// because the owner of the position bundle becomes the owner of the position.
/// The position will start off with 0 liquidity.
/// ### Authority
/// - `position_bundle_authority` - authority that owns the token corresponding
///   to this desired position bundle.
///
/// ### Parameters
/// - `bundle_index` - The bundle index that we'd like to open.
/// - `tick_lower_index` - The tick specifying the lower end of the position
///   range.
/// - `tick_upper_index` - The tick specifying the upper end of the position
///   range.
///
/// #### Special Errors
/// - `InvalidBundleIndex` - If the provided bundle index is out of bounds.
/// - `InvalidTickIndex` - If a provided tick is out of bounds, out of order or
///   not a multiple of
///
/// the tick-spacing in this pool.
