Struct FeatureProvider 

pub struct FeatureProvider { /* private fields */ }

Manages the correspondence between edge labels and feature IDs.

Implementations

impl FeatureProvider

pub fn new() -> Self

Creates a new FeatureProvider.

pub fn is_empty(&self) -> bool

Returns true if the manager has no item.

pub fn len(&self) -> usize

Returns the number of items.

pub fn add_feature_set(&mut self, feature_set: FeatureSet) -> Result<NonZeroU32>

Adds a feature set and returns its ID.

Errors

The number of features must be less than 2^32 - 1.

Trait Implementations

impl Archive for FeatureProvider

where Vec<FeatureSet>: 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 = ArchivedFeatureProvider

The archived representation of this type.

type Resolver = FeatureProviderResolver

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 FeatureProvider

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

Formats the value using the given formatter.

impl Default for FeatureProvider

fn default() -> FeatureProvider

Returns the “default value” for a type.

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

where Vec<FeatureSet>: Archive, <Vec<FeatureSet> as Archive>::Archived: Deserialize<Vec<FeatureSet>, __D>,

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

Deserializes using the given deserializer

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

where Vec<FeatureSet>: 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.
