//! File io implementation.
//!
//! # How to build `FileIO`
//!
//! `FileIO` uses explicit `StorageFactory` injection for storage creation.
//! We provide convenience constructors for common use cases:
//!
//! ```rust,ignore
//! use iceberg::io::{FileIO, FileIOBuilder};
//! use iceberg::io::{LocalFsStorageFactory, MemoryStorageFactory};
//! use std::sync::Arc;
//!
//! // Build a memory file io for testing
//! let file_io = FileIO::new_with_memory();
//!
//! // Build a local filesystem file io
//! let file_io = FileIO::new_with_fs();
//!
//! // Build with explicit factory and configuration
//! let file_io = FileIOBuilder::new(Arc::new(LocalFsStorageFactory))
//!     .with_prop("key", "value")
//!     .build();
//! ```
//!
//! # How to use `FileIO`
//!
//! Currently `FileIO` provides simple methods for file operations:
//!
//! - `delete`: Delete file.
//! - `delete_prefix`: Delete all files with a given prefix.
//! - `exists`: Check if file exists.
//! - `new_input`: Create input file for reading.
//! - `new_output`: Create output file for writing.
