DirEntry in std::fs - Rust (original) (raw)
Struct DirEntry
1.0.0 · Source
pub struct DirEntry(/* private fields */);
Expand description
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.
§Platform-specific behavior
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.
1.0.0 · Source
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.
§Examples
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 .

1.1.0 · Source
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.
§Platform-specific behavior
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.
§Examples
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());
}
}
}
}
1.1.0 · Source
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.
§Platform-specific behavior
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.
§Examples
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());
}
}
}
}
1.1.0 · Source
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:
- “./foo”
- “/the/foo”
- “../../foo”
§Examples
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());
}
}
