[bug] debian test failure

Hi, I recently package your crate for debian. The tests fail though:

This is caused by salvo, axum, actix-web, include-flate, poem, rocket and warp not yet available in debian. Would you consider disabling the example/ tests? I'd really appreciate it.

What command are you using to compile the crate? You don't need to compile the tests/examples.

[werdahias]

this is the autopkgtest, which test the crate with all features enabled/disabled. I patched out the dependencies mentioned above. The issue is still the same with 6.4.1.

[AzureMarker]

Not all features available in Cargo.toml are intended to be used by a library user. Due to how examples work in Cargo, we need a feature to enable certain dependencies only in example code. Please do not try to compile a build intended for packaging with the example-specific features enabled.

[werdahias]

I patched out the examples in Cargo.toml I don't know why the autopkgtest fails still

[AzureMarker]

The example declarations aren't required for cargo to recognize the examples. They just add more details (ex. required features).

I'm going to close this issue since it's not a problem with the library (the configuration is working as expected).
