1.1.0[−][src]Struct std::fs::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
