File Id
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

:
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:?}");
