Struct guppy::graph::feature::feature_list::FeatureList
source · [−]pub struct FeatureList<'g> { /* private fields */ }Expand description
A sorted, deduplicated list of features from a single package.
This provides a convenient way to query and print out lists of features.
Returned by methods on FeatureSet.
Implementations
sourceimpl<'g> FeatureList<'g>
impl<'g> FeatureList<'g>
sourcepub fn new(
package: PackageMetadata<'g>,
labels: impl IntoIterator<Item = FeatureLabel<'g>>
) -> Self
pub fn new(
package: PackageMetadata<'g>,
labels: impl IntoIterator<Item = FeatureLabel<'g>>
) -> Self
Creates a new FeatureList from a package and an iterator over feature labels.
sourcepub fn package(&self) -> &PackageMetadata<'g>
pub fn package(&self) -> &PackageMetadata<'g>
Returns the package corresponding to this feature list.
sourcepub fn contains(&self, label: FeatureLabel<'_>) -> bool
pub fn contains(&self, label: FeatureLabel<'_>) -> bool
Returns true if this feature list contains this feature label.
sourcepub fn has_base(&self) -> bool
pub fn has_base(&self) -> bool
Returns true if this feature list contains the “base” feature.
The “base” feature represents the package with no features enabled.
sourcepub fn has_named_feature(&self, feature_name: &str) -> bool
pub fn has_named_feature(&self, feature_name: &str) -> bool
Returns true if this feature list contains the specified named feature.
sourcepub fn has_optional_dependency(&self, dep_name: &str) -> bool
pub fn has_optional_dependency(&self, dep_name: &str) -> bool
Returns true if this feature list contains the specified optional dependency.
sourcepub fn labels(&self) -> &[FeatureLabel<'g>]
pub fn labels(&self) -> &[FeatureLabel<'g>]
Returns the list of labels as a slice.
This slice is guaranteed to be sorted and unique.
sourcepub fn named_features(&self) -> impl Iterator<Item = &'g str> + '_
pub fn named_features(&self) -> impl Iterator<Item = &'g str> + '_
Returns an iterator containing all named features.
The iterator is guaranteed to be sorted and unique.
sourcepub fn optional_deps(&self) -> impl Iterator<Item = &'g str> + '_
pub fn optional_deps(&self) -> impl Iterator<Item = &'g str> + '_
Returns an iterator containing all optional dependencies.
The iterator is guaranteed to be sorted and unique.

pub fn iter<'a>(&'a self) -> Iter<'g, 'a>ⓘNotable traits for Iter<'g, 'a>impl<'g, 'a> Iterator for Iter<'g, 'a> type Item = FeatureId<'g>;
Returns a borrowed iterator over feature IDs.
sourcepub fn display_features<'a>(&'a self) -> DisplayFeatures<'g, 'a>
pub fn display_features<'a>(&'a self) -> DisplayFeatures<'g, 'a>
Returns a pretty-printer over the list of feature labels.
sourcepub fn into_labels(self) -> Vec<FeatureLabel<'g>>ⓘNotable traits for Vec<u8, A>impl<A> Write for Vec<u8, A> where
A: Allocator,
pub fn into_labels(self) -> Vec<FeatureLabel<'g>>ⓘNotable traits for Vec<u8, A>impl<A> Write for Vec<u8, A> where
A: Allocator,
A: Allocator,
Returns a vector of feature labels.
The vector is guaranteed to be sorted and unique.
