Struct std::fs::FileType

pub struct FileType(_);

A structure representing a type of file with accessors for each file type. It is returned by Metadata::file_type method.

Methods

impl FileType

pub fn is_dir(&self) -> bool

Test whether this file type represents a directory.

Examples

use std::fs;

let metadata = fs::metadata("foo.txt")?;
let file_type = metadata.file_type();

assert_eq!(file_type.is_dir(), false);

pub fn is_file(&self) -> bool

Test whether this file type represents a regular file.

Examples

use std::fs;

let metadata = fs::metadata("foo.txt")?;
let file_type = metadata.file_type();

assert_eq!(file_type.is_file(), true);

pub fn is_symlink(&self) -> bool

Test whether this file type represents a symbolic link.

The underlying Metadata struct needs to be retrieved with the fs::symlink_metadata function and not the fs::metadata function. The fs::metadata function follows symbolic links, so is_symlink would always return false for the target file.

Examples

use std::fs;

let metadata = fs::symlink_metadata("foo.txt")?;
let file_type = metadata.file_type();

assert_eq!(file_type.is_symlink(), false);
