Module metadata 

File metadata operations including size calculation, checksums, and file queries.

This module provides functions for:

• Directory size calculation (recursive)
• SHA-256 checksum generation (single and parallel)
• File existence and readability checks
• File modification time queries and comparisons

Examples

use agpm_cli::utils::fs::metadata::{calculate_checksum, dir_size, file_exists_and_readable};
use std::path::Path;

// Check if file is readable
if file_exists_and_readable(Path::new("important.txt")) {
    // Calculate checksum for integrity verification
    let checksum = calculate_checksum(Path::new("important.txt"))?;
    println!("File checksum: {}", checksum);
}

// Calculate directory size
let size = dir_size(Path::new("cache"))?;
println!("Cache size: {} bytes", size);

Functions

calculate_checksum

Calculates the SHA-256 checksum of a file.

calculate_checksums_parallel

Calculates SHA-256 checksums for multiple files concurrently.

compare_file_times

Compares the modification times of two files.

dir_size

Calculates the total size of a directory and all its contents recursively.

file_exists_and_readable

Checks if a file exists and is readable.

get_directory_size

Asynchronously calculates the total size of a directory and all its contents.

get_modified_time

Gets the modification time of a file.
