Enum StandardFeatures

pub enum StandardFeatures {
    None,
    Default,
    All,
}

Describes one of the standard sets of features recognized by Cargo: none, all or default.

StandardFeatures implements FeatureFilter<'g>, so it can be passed in as a feature filter wherever necessary.

Variants

None

No features. Equivalent to a build with --no-default-features.

Default

Default features. Equivalent to a standard cargo build.

All

All features. Equivalent to cargo build --all-features.

Implementations

impl StandardFeatures

pub const VALUES: &'static [Self; 3] = _

A list of all the possible values of StandardFeatures.

Trait Implementations

impl Clone for StandardFeatures

fn clone(&self) -> StandardFeatures

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for StandardFeatures

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

Formats the value using the given formatter.

impl<'g> FeatureFilter<'g> for StandardFeatures

fn accept( &mut self, graph: &FeatureGraph<'g>, feature_id: FeatureId<'g>, ) -> bool

Returns true if this feature ID should be selected in the graph.

impl Hash for StandardFeatures

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl Ord for StandardFeatures

fn cmp(&self, other: &StandardFeatures) -> 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,

Restrict a value to a certain interval.

impl PartialEq for StandardFeatures

fn eq(&self, other: &StandardFeatures) -> 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 StandardFeatures

fn partial_cmp(&self, other: &StandardFeatures) -> 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.
