Enum FeatureRef 

pub enum FeatureRef {
    Local {
        name: String,
    },
    Namespaced {
        package: String,
        feature: String,
    },
    DepActivation {
        dep_name: String,
    },
}

Reference to a feature by name. Either local ("derive" → this package’s derive feature) or namespaced ("serde/derive" → another crate’s feature).

Variants

Local

Feature of this package.

Fields

name: String

Namespaced

Feature of a different package: serde/derive.

Fields

package: String

feature: String

DepActivation

Pseudo-feature that activates an optional dependency (Cargo’s dep:foo syntax).

Fields

dep_name: String

Implementations

impl FeatureRef

pub fn parse(s: &str) -> Self

Parse serde/derive / dep:foo / derive shapes into the matching typed variant.

Trait Implementations

impl Clone for FeatureRef

fn clone(&self) -> FeatureRef

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for FeatureRef

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for FeatureRef

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Eq for FeatureRef

impl PartialEq for FeatureRef

fn eq(&self, other: &FeatureRef) -> 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 Serialize for FeatureRef

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.
