Can't unpack zero sized file created by dotnet tar

[sobczyk]

Dotnet Tar creates empty files that cause error in tar-rs

Program.cs (preferably use .net 8)

using System.Formats.Tar;

MemoryStream ms = new(0);
var testStream = File.OpenWrite("trigger.tar");
TarWriter archive = new(testStream);
PaxTarEntry entry = new(TarEntryType.RegularFile, "zeroed");
entry.DataStream = ms;
archive.WriteEntry(entry);
archive.Dispose();
testStream.Dispose();

rust code:

use std::fs::File;
use tar::Archive;

fn main() {
    let file = File::open("trigger.tar").unwrap();
    let mut archive = Archive::new(file);
    let entries = archive.entries().unwrap();
    for entry in entries {
        let entry = entry.unwrap();
        println!("{:?}", entry.header());
    }
}

what I get:

thread 'main' panicked at src/main.rs:9:27:
called `Result::unwrap()` on an `Err` value: Custom { kind: Other, error: "numeric field was not a number:  when getting size for zeroed" }
note: run with `RUST_BACKTRACE=1` environment variable to display a backtrace

example expected: ( "trigger.tar" created using GNU tar)

GnuHeader { entry_size: 0, size: 0, path: "zeroed", link_name: None, mode: 664, uid: 1000, gid: 1000, mtime: 1700484015, username: Some("sobczyk"), groupname: Some("sobczyk"), cksum: 5276, cksum_valid: true, is_extended: false, sparse: [] }

I attach a test project directory
Use:

dotnet run
cargo run
