# 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

#### `pub fn is_symlink(&self) -> bool`[src]

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
