Struct FeatureOpts

pub struct FeatureOpts {
    decouple_host_deps: bool,
    decouple_dev_deps: bool,
    ignore_inactive_targets: bool,
    compare: bool,
}

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).

Implementations

impl FeatureOpts

pub fn new( ws: &Workspace<'_>, has_dev_units: HasDevUnits, force_all_targets: ForceAllTargets, ) -> CargoResult<FeatureOpts>

pub fn new_behavior( behavior: ResolveBehavior, has_dev_units: HasDevUnits, ) -> FeatureOpts

Creates a new FeatureOpts for the given behavior.

Trait Implementations

impl Default for FeatureOpts

fn default() -> FeatureOpts

Returns the “default value” for a type.

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.
