Crate file_type_enum

Simple and minimal enum with one variant for each file type.

This crate is very, very small. But it may save you from writing 120 redundant lines in your projects.

Size for each target family:

• unix.rs - ~120 SLOC (Source lines of code)
• windows.rs - ~70 SLOC (Source lines of code)

Here are some examples in unix, but file_type_enum works on windows too!

Examples:

use file_type_enum::FileType;

fn main() {
    let path = "/tmp";
    let file_type = FileType::try_from_path(path).unwrap();

    println!("There's a {} at {}!", file_type, path);
    // Outputs: "There's a directory at /tmp!"
}

Note: FileType::try_from_path() fails if:

• The user lacks permissions to read metadata on the path.
• Path does not exist.

---

By default, FileType::try_from_path() will follow symlinks, so the Result will never retrieve a FileType::Symlink, however, we have a specific function if you don't want it to follow symlinks:

use file_type_enum::FileType;

fn main() {
    let path = "/dev/stdout";
    let file_type = FileType::try_from_symlink_path(path).unwrap();

    println!("There's a {} at {}!", file_type, path);
    // Outputs: "There's a symbolic link at /dev/stdout!"
}

---

Enum FileType:

There are up to 7 file types in unix and 3 in windows:

pub enum FileType {
    File,
    Directory,
    Symlink,
    BlockDevice, // unix only
    CharDevice,  // unix only
    Fifo,        // unix only
    Socket,      // unix only
}

Bool short hands for each type

Besides granting a variant for each file type, there is also a function for each type to serve as a short hand to return a bool

use file_type_enum::FileType;

fn main() {
    let path = ".git";
    let file_type = FileType::try_from_path(path).unwrap();

    if !file_type.is_dir() {
        println!("We are not inside of a git repository.");
    }
}

---

Last example, passing the io::Error around.

Show file type for every env::args():

use file_type_enum::FileType;

use std::{env, io};

fn main() -> Result<(), io::Error> {
    for path in env::args().skip(1) {
        let file_type = FileType::try_from_path(&path)?;
        println!("'{}' is a {}.", path, file_type);
    }
    Ok(())
}
