Trait PathExt

pub trait PathExt {
    // Required methods
    fn size_on_disk(&self) -> Result<u64>;
    fn size_on_disk_fast(&self, metadata: &Metadata) -> Result<u64>;
}

An extension trait for std::path::Path to retrieve the on-disk size of a given file.

Required Methods

fn size_on_disk(&self) -> Result<u64>

Get the on-disk size of the file at the given Path.

use std::path::Path;
use filesize::PathExt;

let realsize = Path::new("Cargo.toml").size_on_disk()?;

fn size_on_disk_fast(&self, metadata: &Metadata) -> Result<u64>

Get the on-disk size of the file at the given Path, using the provided std::fs::Metadata instance if possible.

This should normally only be used when metadata is cheaply available, for instance, during a directory traversal, or when metadata will be used for other purposes.

use std::path::Path;
use filesize::PathExt;

let path = Path::new("Cargo.toml");
let metadata = path.symlink_metadata()?;
let realsize = path.size_on_disk_fast(&metadata)?;
