When extracting cbindgen-0.24.3-x86_64-apple-darwin.tar.gz using the following equivalent code:

use flate2::read::GzDecoder;
use tar::Archive;

let tar = GzDecoder::new(dat);
Archive::new(tar).unpack(path)?;

where dat is some readable that is pipelined from the downloading stage, I got:

/var/folders/4h/3pck4_r16tn6960znvv4w0nw0000gn/T/.tmp7GLCIo/bin-cbindgen
└── GNUSparseFile.0
    └── cbindgen

1 directory, 1 file

Using file cbindgen shows that it is just data, does not have executable set and cannot be executed after chmod +x cbindgen.

While it should be:

/var/folders/4h/3pck4_r16tn6960znvv4w0nw0000gn/T/.tmp7GLCIo/bin-cbindgen
└── cbindgen

I used bsdtar 3.5.1 - libarchive 3.5.1 zlib/1.2.11 liblzma/5.0.5 bz2lib/1.0.8 and it handles it just fine.

Here's the relevant part of the Cargo.toml:

flate2 = { version = "1.0.24", features = ["zlib-ng"], default-features = false }
tar = "0.4.38"

I discovered this bug in cargo-bins/cargo-binstall#174
