I added some commits to update the dependencies to latest.

Something is not right:

$ target/debug/btf dump /boot/vmlinux-$(uname -r)
thread 'main' panicked at 'Mismatch between definition and access of `format`. Could not downcast to btf::DumpFormat, need to downcast to alloc::string::String
', src/main.rs:113:17
note: run with `RUST_BACKTRACE=1` environment variable to display a backtrace

Thanks, sorry about that. i wanted to write an integration test but it seems that there's nothing currently set up for compiling the BTF and then dumping it.

EDIT: the test would look something like:

diff --git a/tests/tests.rs b/tests/tests.rs
new file mode 100644
index 0000000..8fee9f0

+    let std::process::Output {
+        status,
+        stdout,
+        stderr,
+    } = cmd
+        .arg("dump")
+        .arg(path-to-btf)
+        .output()
+        .unwrap();
+    let stdout = std::str::from_utf8(&stdout);
+    let stderr = std::str::from_utf8(&stderr);
+    assert_eq!(
+        status.code(),
+        Some(0),
+        "{:?} failed: stdout={:?} stderr={:?}",
+        cmd,
+        stdout,
+        stderr
+    );
+}

Works now, thanks! Do you want me to create a new v0.0.4 release right away?

[tamird]

Yes, that would be helpful!

[anakryiko]

ok, release v0.0.4 is pushed out (https://github.com/anakryiko/btfdump/releases/tag/v0.0.4, https://crates.io/crates/btfdump/0.0.4)
