Some crates have a myriad of features, and it is very easy to accidentally mess up imports in a way that `cargo check --all-features` works, but only compiling with only a subset of features breaks. For this scenario, cargo check-all-features can help, as it will attempt to compile all feature permutations. We can even add this to the default CI, even for crates like vhost that have incompatible features, due to cargo-all-features allowing the elimination of incompatible features from the test matrix [1]. Some usecases where this could have been helpful is in vm-memory, where we have tens of feature permutations, and some of them invariably get broken regularly [2], or in crates that have no-std support that is offered via an opt-out 'std' feature [3] [1]: https://crates.io/crates/cargo-all-features#options [2]: rust-vmm/vm-memory#350 [3]: rust-vmm/vm-allocator#107 Signed-off-by: Patrick Roy <roypat@amazon.co.uk>
