Cargo Features
x86 has no features set by default.
[dependencies]
x86 = { version = "0.52.0", features = ["performance-counter", "utest", "vmtest", "unstable"] }- performance-counter = csv, phf, phf_codegen, serde_json
-
Affects
x86::perfcnt… - utest
-
Note we have to choose between regular tests and x86test at the moment, so we use features (limitation in https://github.com/rust-lang/rust/issues/50297) Run user-space tests, i.e. regular #[test]
- vmtest
-
Run VM tests, i.e., the #[x86test] ones
- unstable
Features from optional dependencies
In crates that don't use the dep: syntax, optional dependencies automatically become Cargo features. These features may have been created by mistake, and this functionality may be removed in the future.
