Struct FeatureSet 

pub struct FeatureSet { /* private fields */ }

Manages a set of features for each label.

Implementations

impl FeatureSet

pub fn new( unigram: &[NonZeroU32], bigram_right: &[Option<NonZeroU32>], bigram_left: &[Option<NonZeroU32>], ) -> Self

Creates a new FeatureSet.

pub fn unigram(&self) -> &[NonZeroU32]

Gets uni-gram feature IDs.

pub fn bigram_right(&self) -> &[Option<NonZeroU32>]

Gets right bi-gram feature IDs.

pub fn bigram_left(&self) -> &[Option<NonZeroU32>]

Gets left bi-gram feature IDs

Trait Implementations

impl Archive for FeatureSet

where Vec<NonZeroU32>: Archive, Vec<Option<NonZeroU32>>: Archive,

const COPY_OPTIMIZATION: CopyOptimization<Self>

An optimization flag that allows the bytes of this type to be copied directly to a writer instead of calling serialize.

type Archived = ArchivedFeatureSet

The archived representation of this type.

type Resolver = FeatureSetResolver

The resolver for this type. It must contain all the additional information from serializing needed to make the archived type from the normal type.

fn resolve(&self, resolver: Self::Resolver, out: Place<Self::Archived>)

Creates the archived version of this value at the given position and writes it to the given output.

impl Debug for FeatureSet

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

Formats the value using the given formatter.

impl Default for FeatureSet

fn default() -> FeatureSet

Returns the “default value” for a type.

impl<__D: Fallible + ?Sized> Deserialize<FeatureSet, __D> for Archived<FeatureSet>

where Vec<NonZeroU32>: Archive, <Vec<NonZeroU32> as Archive>::Archived: Deserialize<Vec<NonZeroU32>, __D>, Vec<Option<NonZeroU32>>: Archive, <Vec<Option<NonZeroU32>> as Archive>::Archived: Deserialize<Vec<Option<NonZeroU32>>, __D>,

fn deserialize( &self, deserializer: &mut __D, ) -> Result<FeatureSet, <__D as Fallible>::Error>

Deserializes using the given deserializer

impl<__S: Fallible + ?Sized> Serialize<__S> for FeatureSet

where Vec<NonZeroU32>: Serialize<__S>, Vec<Option<NonZeroU32>>: Serialize<__S>,

fn serialize( &self, serializer: &mut __S, ) -> Result<<Self as Archive>::Resolver, <__S as Fallible>::Error>

Writes the dependencies for the object and returns a resolver that can create the archived type.
