Struct Feature 

pub struct Feature<'f>(/* private fields */);

Methods from Deref<Target = Cow<'f, str>>

pub fn to_mut(&mut self) -> &mut <B as ToOwned>::Owned

Acquires a mutable reference to the owned form of the data.

Clones the data if it is not already owned.

Examples

use std::borrow::Cow;

let mut cow = Cow::Borrowed("foo");
cow.to_mut().make_ascii_uppercase();

assert_eq!(
  cow,
  Cow::Owned(String::from("FOO")) as Cow<'_, str>
);

Trait Implementations

impl<'f, __AsT: ?Sized> AsMut<__AsT> for Feature<'f>

where Cow<'f, str>: AsMut<__AsT>,

fn as_mut(&mut self) -> &mut __AsT

Converts this type into a mutable reference of the (usually inferred) input type.

impl<'f, __AsT: ?Sized> AsRef<__AsT> for Feature<'f>

where Cow<'f, str>: AsRef<__AsT>,

fn as_ref(&self) -> &__AsT

Converts this type into a shared reference of the (usually inferred) input type.

impl<'f> Clone for Feature<'f>

fn clone(&self) -> Feature<'f>

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl<'f> Debug for Feature<'f>

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

Formats the value using the given formatter.

impl<'f> DerefMut for Feature<'f>

fn deref_mut(&mut self) -> &mut Self::Target

Mutably dereferences the value.

impl<'de, 'f> Deserialize<'de> for Feature<'f>

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Display for Feature<'_>

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

Formats the value using the given formatter.

impl From<String> for Feature<'static>

fn from(s: String) -> Self

Converts to this type from the input type.

impl<'f> FromIterator<Feature<'f>> for FeatureSet<'f>

fn from_iter<T: IntoIterator<Item = Feature<'f>>>(iter: T) -> Self

Creates a value from an iterator.

impl<'f> Hash for Feature<'f>

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<'f> Ord for Feature<'f>

fn cmp(&self, other: &Feature<'f>) -> 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<'f> PartialEq for Feature<'f>

fn eq(&self, other: &Feature<'f>) -> 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<'f> PartialOrd for Feature<'f>

fn partial_cmp(&self, other: &Feature<'f>) -> 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.

impl<'f> Serialize for Feature<'f>

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

where __S: Serializer,

Serialize this value into the given Serde serializer.

impl<'f> Deref for Feature<'f>

type Target = Cow<'f, str>

The resulting type after dereferencing.

fn deref(&self) -> &Self::Target

Dereferences the value.
