pub struct DirEntry(/* private fields */);
Entries returned by the ReadDir iterator.
An instance of DirEntry represents an entry inside of a directory on the filesystem. Each entry can be inspected via methods to learn about the full path or possibly other metadata through per-platform extension traits.
On Unix, the DirEntry struct contains an internal reference to the open directory. Holding DirEntry objects will consume a file handle even after the ReadDir iterator is dropped.
Note that this may change in the future.
impl DirEntry
pub fn path(&self) -> PathBuf
Returns the full path to the file that this entry represents.
The full path is created by joining the original path to read_dir with the filename of this entry.
use std::fs;
fn main() -> std::io::Result<()> {
for entry in fs::read_dir(".")? {
let dir = entry?;
println!("{:?}", dir.path());
}
Ok(())
}This prints output like:
"./whatever.txt" "./foo.html" "./hello_world.rs"
The exact text, of course, depends on what files you have in ..
pub fn metadata(&self) -> Result<Metadata>
Returns the metadata for the file that this entry points at.
This function will not traverse symlinks if this entry points at a symlink. To traverse symlinks use fs::metadata or fs::File::metadata.
On Windows this function is cheap to call (no extra system calls needed), but on Unix platforms this function is the equivalent of calling symlink_metadata on the path.
use std::fs;
if let Ok(entries) = fs::read_dir(".") {
for entry in entries {
if let Ok(entry) = entry {
// Here, `entry` is a `DirEntry`.
if let Ok(metadata) = entry.metadata() {
// Now let's show our entry's permissions!
println!("{:?}: {:?}", entry.path(), metadata.permissions());
} else {
println!("Couldn't get metadata for {:?}", entry.path());
}
}
}
}pub fn file_type(&self) -> Result<FileType>
Returns the file type for the file that this entry points at.
This function will not traverse symlinks if this entry points at a symlink.
On Windows and most Unix platforms this function is free (no extra system calls needed), but some Unix platforms may require the equivalent call to symlink_metadata to learn about the target file type.
use std::fs;
if let Ok(entries) = fs::read_dir(".") {
for entry in entries {
if let Ok(entry) = entry {
// Here, `entry` is a `DirEntry`.
if let Ok(file_type) = entry.file_type() {
// Now let's show our entry's file type!
println!("{:?}: {:?}", entry.path(), file_type);
} else {
println!("Couldn't get file type for {:?}", entry.path());
}
}
}
}pub fn file_name(&self) -> OsString
Returns the file name of this directory entry without any leading path component(s).
As an example, the output of the function will result in “foo” for all the following paths:
use std::fs;
if let Ok(entries) = fs::read_dir(".") {
for entry in entries {
if let Ok(entry) = entry {
// Here, `entry` is a `DirEntry`.
println!("{:?}", entry.file_name());
}
}
