Expand description

Options for how the feature resolver works.

Fields§

§decouple_host_deps: bool

Build deps and proc-macros will not share features with other dep kinds, and so won’t artifact targets. In other terms, if true, features associated with certain kinds of dependencies will only be unified together. If false, there is only one namespace for features, unifying all features across all dependencies, no matter what kind.

§decouple_dev_deps: bool

Dev dep features will not be activated unless needed.

§ignore_inactive_targets: bool

Targets that are not in use will not activate features.

§compare: bool

If enabled, compare against old resolver (for testing).

Layout§

Note: Most layout information is completely unstable and may even differ between compilations. The only exception is types with certain repr(...) attributes. Please see the Rust Reference’s “Type Layout” chapter for details on type layout guarantees.
