1.1.0[][src]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[src]

pub fn is_dir(&self) -> bool[src]

Tests whether this file type represents a directory. The result is mutually exclusive to the results of is_file and is_symlink; only zero or one of these tests may pass.

Examples

fn main() -> std::io::Result<()> {
    use std::fs;

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

    assert_eq!(file_type.is_dir(), false);
    Ok(())
}Run

pub fn is_file(&self) -> bool[src]

Tests whether this file type represents a regular file. The result is mutually exclusive to the results of is_dir and is_symlink; only zero or one of these tests may pass.

Examples

fn main() -> std::io::Result<()> {
    use std::fs;

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

    assert_eq!(file_type.is_file(), true);
    Ok(())
}Run

Tests whether this file type represents a symbolic link. The result is mutually exclusive to the results of is_dir and is_file; only zero or one of these tests may pass.

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;

fn main() -> std::io::Result<()> {
    let metadata = fs::symlink_metadata("foo.txt")?;
    let file_type = metadata.file_type();

    assert_eq!(file_type.is_symlink(), false);
    Ok(())
}Run
