acorn-lib 0.1.59

//! # IO Utilities
//!
//! Module to isolate input/output operations to enhance portability
//!
//! ## Example Uses
//!
//! ### Perform file read and write operations
//! ```ignore
//! use acorn::util::{checksum, read_file, write_file};
//! use std::path::PathBuf;
//!
//! // Verify file integrity
//! assert_eq!(checksum(PathBuf::from("/path/to/file")), "somesha256hashvaluethatisreallylong");
//!
//! // Read file contents
//! let contents = read_file(PathBuf::from("/path/to/this/file"));
//!
//! // Write file contents
//! write_file(PathBuf::from("/path/to/that/file"), contents);
//! ```
