pub struct DirEntry { /* private fields */ }
Expand description

Entries returned by the ReadDir stream.

This is a specialized version of std::fs::DirEntry for usage from the Tokio runtime.

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§

source§

impl DirEntry

source

pub fn ino(&self) -> u64

Returns the underlying d_ino field in the contained dirent structure.

Examples
use tokio::fs;

let mut entries = fs::read_dir(".").await?;
while let Some(entry) = entries.next_entry().await? {
    // Here, `entry` is a `DirEntry`.
    println!("{:?}: {}", entry.file_name(), entry.ino());
}
source§

impl DirEntry

source

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.

Examples
use tokio::fs;

let mut entries = fs::read_dir(".").await?;

while let Some(entry) = entries.next_entry().await? {
    println!("{:?}", entry.path());
}

This prints output like:

"./whatever.txt"
"./foo.html"
"./hello_world.rs"

The exact text, of course, depends on what files you have in ..

source

pub fn file_name(&self) -> OsString

Returns the bare file name of this directory entry without any other leading path component.

Examples
use tokio::fs;

let mut entries = fs::read_dir(".").await?;

while let Some(entry) = entries.next_entry().await? {
    println!("{:?}", entry.file_name());
}
source

pub async fn metadata(&self) -> impl Future<Output = Result<Metadata, Error>>

Returns the metadata 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 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 tokio::fs;

let mut entries = fs::read_dir(".").await?;

while let Some(entry) = entries.next_entry().await? {
    if let Ok(metadata) = entry.metadata().await {
        // Now let's show our entry's permissions!
        println!("{:?}: {:?}", entry.path(), metadata.permissions());
    } else {
        println!("Couldn't get file type for {:?}", entry.path());
    }
}
source

pub async fn file_type(&self) -> impl Future<Output = Result<FileType, Error>>

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 tokio::fs;

let mut entries = fs::read_dir(".").await?;

while let Some(entry) = entries.next_entry().await? {
    if let Ok(file_type) = entry.file_type().await {
        // Now let's show our entry's file type!
        println!("{:?}: {:?}", entry.path(), file_type);
    } else {
        println!("Couldn't get file type for {:?}", entry.path());
    }
}
