Function hash_file 

pub fn hash_file(filename: String) -> FileInfo

Calculate the hash of a file’s contents.

This function reads the contents of the specified file, calculates its MD5 hash, and returns the result as a FileInfo struct.

If the file cannot be opened, read, or its contents cannot be decoded as UTF-8, an error FileInfo with “none” as the hash is returned.

Arguments

• filename - The path to the file for which to calculate the MD5 hash.

Returns

A FileInfo struct containing the filename and MD5 hash of the file’s contents.

Examples

use file_integrity::{hash_file, FileInfo};

let filename = "path/to/your/file.txt".to_string();
let file_info = hash_file(filename);
println!("Filename: {}", file_info.filename);
println!("MD5 Hash: {}", file_info.md5_hash);

Errors

This function can return an error if the file cannot be opened, read, or its contents cannot be decoded as UTF-8.
