Crate safe_write

A crate for safely writing files using an atomic write pattern.

This crate implements a safe file writing strategy that helps prevent file corruption in case of system crashes or power failures. It follows these steps:

1. Creates parent directories if they don’t exist
2. Writes content to a temporary file
3. Ensures the content is fully written to disk
4. Atomically renames the temporary file to the target path

Examples

use safe_write::safe_write;

let content = b"Hello, World!";
safe_write("example.txt", content).expect("Failed to write file");

Platform-specific behavior

On Windows, if the target file exists, it will be explicitly removed before the rename operation since Windows doesn’t support atomic file replacement.
