# Struct std::fs::FileType 1.1.0[−][src]

    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]

Test 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]

Test 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]

Test 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

## Search Tricks

Prefix searches with a type followed by a colon (e.g. `fn:`) to restrict the search to a given type.

Accepted types are: `fn`, `mod`, `struct`, `enum`, `trait`, `type`, `macro`, and `const`.

Search functions by type signature (e.g. `vec -> usize` or `* -> vec`)

Search multiple things at once by splitting your query with comma (e.g. `str,u8` or `String,struct:Vec,test`)
