//! Error types for the Pump.fun SDK.
//!
//! This module defines the `ClientError` enum, which encompasses various error types that can occur when interacting with the Pump.fun program.
//! It includes specific error cases for bonding curve operations, metadata uploads, Solana client errors, and more.
//!
//! The `ClientError` enum provides a comprehensive set of error types to help developers handle and debug issues that may arise during interactions with the Pump.fun program.
//!
//! # Error Types
//!
//! - `BondingCurveNotFound`: The bonding curve account was not found.
//! - `BondingCurveError`: An error occurred while interacting with the bonding curve.
//! - `BorshError`: An error occurred while serializing or deserializing data using Borsh.
//! - `SolanaClientError`: An error occurred while interacting with the Solana RPC client.
//! - `UploadMetadataError`: An error occurred while uploading metadata to IPFS.
//! - `AnchorClientError`: An error occurred while interacting with the Anchor client.
//! - `InvalidInput`: Invalid input parameters were provided.
//! - `InsufficientFunds`: Insufficient funds for a transaction.
//! - `SimulationError`: Transaction simulation failed.
//! - `RateLimitExceeded`: Rate limit exceeded.
