File Id

» Docs

A utility to read file IDs.

Modern file systems assign a unique ID to each file. On Linux and MacOS it is called an inode number, on Windows it is called file index. Together with the device id, a file can be identified uniquely on a device at a given time.

Keep in mind though, that IDs may be re-used at some point.

Example

let file_id = file_id::get_file_id(path).unwrap();

println!("{file_id:?}");

Features

  • serde for serde support, off by default

lib.rs:

Utility for reading inode numbers (Linux, macOS) and file ids (Windows) that uniquely identify a file on a single computer.

Modern file systems assign a unique ID to each file. On Linux and macOS it is called an inode number, on Windows it is called a file id or file index. Together with the device id (Linux, macOS) or the volume serial number (Windows), a file or directory can be uniquely identified on a single computer at a given time.

Keep in mind though, that IDs may be re-used at some point.

Example

let file = tempfile::NamedTempFile::new().unwrap();

let file_id = file_id::get_file_id(file.path()).unwrap();
println!("{file_id:?}");

Example (Windows Only)

let file = tempfile::NamedTempFile::new().unwrap();

let file_id = file_id::get_low_res_file_id(file.path()).unwrap();
println!("{file_id:?}");

let file_id = file_id::get_high_res_file_id(file.path()).unwrap();
println!("{file_id:?}");
