//! # FTP Tasklet
//!
//! This module provides tasklets for FTP file transfer operations (put and get).
//! It's designed to be similar to Spring Batch's FTP capabilities for batch file transfers.
//!
//! ## Features
//!
//! - FTP PUT operations (upload files to FTP server)
//! - FTP GET operations (download files from FTP server)
//! - FTP PUT FOLDER operations (upload entire folder contents to FTP server)
//! - FTP GET FOLDER operations (download entire folder contents from FTP server)
//! - Support for both active and passive FTP modes
//! - Configurable connection parameters
//! - Proper error handling and logging
//! - Builder pattern for easy configuration
//!
//! ## Memory Efficiency Features
//!
//! **Streaming Downloads (Implemented):**
//! - Both `FtpGetTasklet` and `FtpGetFolderTasklet` use `retr()` streaming method
//!   to download files directly from FTP server to local storage without loading
//!   entire files into memory
//! - This approach is memory-efficient for files of any size, from small to very large
//! - Uses proper error type conversion between `std::io::Error` and `FtpError`
//!   through the `io_error_to_ftp_error` helper function
//!
//! **Performance Benefits:**
//! - Constant memory usage regardless of file size
//! - Improved performance for large file transfers
//! - Reduced risk of out-of-memory errors when processing large files
//! - Direct streaming from network to disk without intermediate buffering
//!
//! ## Examples
//!
//! ### FTP PUT Operation
//!
//! ```rust
//! use spring_batch_rs::core::step::{StepBuilder, StepExecution, Step};
//! use spring_batch_rs::tasklet::ftp::FtpPutTaskletBuilder;
//! use std::path::Path;
//!
//! # fn example() -> Result<(), spring_batch_rs::BatchError> {
//! let ftp_put_tasklet = FtpPutTaskletBuilder::new()
//!     .host("ftp.example.com")
//!     .port(21)
//!     .username("user")
//!     .password("password")
//!     .local_file("./local_file.txt")
//!     .remote_file("/remote/path/file.txt")
//!     .passive_mode(true)
//!     .build()?;
//!
//! let step = StepBuilder::new("ftp-upload")
//!     .tasklet(&ftp_put_tasklet)
//!     .build();
//!
//! let mut step_execution = StepExecution::new("ftp-upload");
//! step.execute(&mut step_execution)?;
//! # Ok(())
//! # }
//! ```
//!
//! ### FTP GET Operation (Memory-Efficient Streaming)
//!
//! ```rust
//! use spring_batch_rs::tasklet::ftp::FtpGetTaskletBuilder;
//!
//! # fn example() -> Result<(), spring_batch_rs::BatchError> {
//! // This tasklet streams large files directly to disk without loading into memory
//! let ftp_get_tasklet = FtpGetTaskletBuilder::new()
//!     .host("ftp.example.com")
//!     .username("user")
//!     .password("password")
//!     .remote_file("/remote/path/large_file.zip")  // Works efficiently with any file size
//!     .local_file("./downloaded_large_file.zip")
//!     .build()?;
//! # Ok(())
//! # }
//! ```
//!
//! ### FTPS (Secure FTP) Operations
//!
//! ```rust
//! use spring_batch_rs::tasklet::ftp::{FtpPutTaskletBuilder, FtpGetTaskletBuilder};
//!
//! # fn example() -> Result<(), spring_batch_rs::BatchError> {
//! // Secure upload using FTPS (FTP over TLS)
//! let secure_upload = FtpPutTaskletBuilder::new()
//!     .host("secure-ftp.example.com")
//!     .port(990)  // Common FTPS port
//!     .username("user")
//!     .password("password")
//!     .local_file("./sensitive_data.txt")
//!     .remote_file("/secure/path/data.txt")
//!     .secure(true)  // Enable FTPS
//!     .build()?;
//!
//! // Secure download using FTPS with streaming for memory efficiency
//! let secure_download = FtpGetTaskletBuilder::new()
//!     .host("secure-ftp.example.com")
//!     .port(990)
//!     .username("user")
//!     .password("password")
//!     .remote_file("/secure/path/confidential.zip")
//!     .local_file("./confidential.zip")
//!     .secure(true)  // Enable FTPS
//!     .build()?;
//! # Ok(())
//! # }
//! ```
