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

/// Open a position in a Whirlpool. A unique token will be minted to represent
/// the position in the users wallet. Additional Metaplex metadata is appended
/// to identify the token. The position will start off with 0 liquidity.
/// ### Parameters
/// - `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
/// - `InvalidTickIndex` - If a provided tick is out of bounds, out of order or
///   not a multiple of
///
/// the tick-spacing in this pool.
