Enum guppy::errors::FeatureGraphWarning

#[non_exhaustive]
pub enum FeatureGraphWarning {
    MissingFeature {
        stage: FeatureBuildStage,
        package_id: PackageId,
        feature_name: String,
    },

Describes warnings emitted during feature graph construction.

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

MissingFeature

A feature that was requested is missing from a package.

Fields

stage: FeatureBuildStage

The stage of building the feature graph where the warning occurred.

package_id: PackageId

The package ID for which the feature was requested.

feature_name: String

The name of the feature.

SelfLoop

A self-loop was discovered.

Fields

package_id: PackageId

The package ID for which the self-loop was discovered.

feature_name: String

The name of the feature for which the self-loop was discovered.

Trait Implementations

impl Clone for FeatureGraphWarning

fn clone(&self) -> FeatureGraphWarning

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for FeatureGraphWarning

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Display for FeatureGraphWarning

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Ord for FeatureGraphWarning

fn cmp(&self, other: &FeatureGraphWarning) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Self

where Self: Sized,

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Self

where Self: Sized,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Self

where Self: Sized + PartialOrd,

Restrict a value to a certain interval.

impl PartialEq for FeatureGraphWarning

fn eq(&self, other: &FeatureGraphWarning) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl PartialOrd for FeatureGraphWarning

fn partial_cmp(&self, other: &FeatureGraphWarning) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

fn lt(&self, other: &Rhs) -> bool

Tests less than (for self and other) and is used by the < operator.

fn le(&self, other: &Rhs) -> bool

Tests less than or equal to (for self and other) and is used by the <= operator.

fn gt(&self, other: &Rhs) -> bool

Tests greater than (for self and other) and is used by the > operator.

fn ge(&self, other: &Rhs) -> bool

Tests greater than or equal to (for self and other) and is used by the >= operator.
