Trait Implementations

impl Clone for Features

fn clone(&self) -> Features

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Features

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

Formats the value using the given formatter.

impl Deref for Features

type Target = BoxedSlicePrefix<Feature, BoundedU8<0, { Features::COUNT_MAX }>>

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 IntoIterator for Features

type Item = Feature

The type of the elements being iterated over.

type IntoIter = IntoIter<<Features as IntoIterator>::Item>

Which kind of iterator are we turning this into?

fn into_iter(self) -> Self::IntoIter

Creates an iterator from a value.

impl Ord for Features

fn cmp(&self, other: &Features) -> 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 Packable for Features

type UnpackError = Error

The error type that can be returned if some semantic error occurs while unpacking.

type UnpackVisitor = <BoxedSlicePrefix<Feature, BoundedU8<0, { Features::COUNT_MAX }>> as Packable>::UnpackVisitor

FIXME: docs

fn pack<P: Packer>(&self, packer: &mut P) -> Result<(), P::Error>

Packs this value into the given [Packer].

fn unpack<U: Unpacker, const VERIFY: bool>( unpacker: &mut U, visitor: &Self::UnpackVisitor, ) -> Result<Self, UnpackError<Self::UnpackError, U::Error>>

Unpacks this value from the given [Unpacker]. The VERIFY generic parameter can be used to skip additional syntactic checks.

impl PartialEq for Features

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

fn partial_cmp(&self, other: &Features) -> 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 TryFrom<BTreeSet<Feature>> for Features

type Error = Error

The type returned in the event of a conversion error.

fn try_from(features: BTreeSet<Feature>) -> Result<Self, Self::Error>

Performs the conversion.

impl TryFrom<Vec<Feature>> for Features

type Error = Error

The type returned in the event of a conversion error.

fn try_from(features: Vec<Feature>) -> Result<Self, Self::Error>

Performs the conversion.
