Struct std::fs::DirEntry 1.0.0[−][src]
pub struct DirEntry(_);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.
Implementations
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(())
}RunThis prints output like:
"./whatever.txt"
"./foo.html"
"./hello_world.rs"The exact text, of course, depends on what files you have in ..
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());
}
}
}
}RunReturns 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());
}
}
}
