//! This code was AUTOGENERATED using the Codama library.
use carbon_core::{account_utils::next_account, deserialize::ArrangeAccounts};
/// Close a bundled position in a Whirlpool.
/// ### 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 close.
///
/// #### Special Errors
/// - `InvalidBundleIndex` - If the provided bundle index is out of bounds.
/// - `ClosePositionNotEmpty` - The provided position account is not empty.
