Struct Utf8DirEntry

Source

pub struct Utf8DirEntry { /* private fields */ }

Expand description

Entries returned by the ReadDirUtf8 iterator.

An instance of Utf8DirEntry 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.

Implementations§

Source §

impl Utf8DirEntry

Source

pub fn path(&self) -> &Utf8Path

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 camino::Utf8Path;

fn main() -> std::io::Result<()> {
    for entry in Utf8Path::new(".").read_dir_utf8()? {
        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 ..

Source

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 Utf8Path::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 camino::Utf8Path;

if let Ok(entries) = Utf8Path::new(".").read_dir_utf8() {
    for entry in entries {
        if let Ok(entry) = entry {
            // Here, `entry` is a `Utf8DirEntry`.
            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());
            }
        }
    }
}

Source

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.

§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 camino::Utf8Path;

if let Ok(entries) = Utf8Path::new(".").read_dir_utf8() {
    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());
            }
        }
    }
}

Source

pub fn file_name(&self) -> &str

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

§Examples

use camino::Utf8Path;

if let Ok(entries) = Utf8Path::new(".").read_dir_utf8() {
    for entry in entries {
        if let Ok(entry) = entry {
            // Here, `entry` is a `DirEntry`.
            println!("{}", entry.file_name());
        }
    }
}
