Fields

name: String

encoding: String

default_word_cost: i16

default_left_context_id: u16

default_right_context_id: u16

default_field_value: String

flexible_csv: bool

skip_invalid_cost_or_id: bool

normalize_details: bool

connection_id_mapping: bool

Reorder connection-cost context IDs by frequency at build time so that frequently-used connection-matrix cells cluster in cache. Optional and defaults to false; when false the field is omitted from metadata.json so existing files stay byte-identical, and the build output is unchanged.

context_id_map: Option<ContextIdMap>

The context-ID permutation that was applied when this dictionary was built.

Written into the built metadata.json when connection_id_mapping is on, so that anything compiled later against this dictionary — most importantly a detailed user dictionary — can be relabeled into the same ID space. Absent (and omitted from the file) for an un-remapped dictionary, which keeps those builds byte-identical. Source metadata.json files carry only the boolean flag.

dictionary_schema: Schema

user_dictionary_schema: Schema

model_info: Option<ModelInfo>

Implementations

impl Metadata

pub fn new( name: String, encoding: String, simple_word_cost: i16, default_left_context_id: u16, default_right_context_id: u16, default_field_value: String, flexible_csv: bool, skip_invalid_cost_or_id: bool, normalize_details: bool, schema: Schema, userdic_schema: Schema, ) -> Self

pub fn load(data: &[u8]) -> LinderaResult<Self>

Load metadata from binary data (JSON format). This provides a consistent interface with other dictionary components.

pub fn load_or_default(data: &[u8], default_fn: fn() -> Self) -> Self

Load metadata with fallback to default values. This is used when feature flags are disabled and data might be empty.

Trait Implementations

impl Archive for Metadata

where String: Archive, i16: Archive, u16: Archive, bool: Archive, Option<ContextIdMap>: Archive, Schema: Archive, Option<ModelInfo>: 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 = ArchivedMetadata

The archived representation of this type.

type Resolver = MetadataResolver

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 Clone for Metadata

fn clone(&self) -> Metadata

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Default for Metadata

fn default() -> Self

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for Metadata

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

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

where String: Archive, <String as Archive>::Archived: Deserialize<String, __D>, i16: Archive, <i16 as Archive>::Archived: Deserialize<i16, __D>, u16: Archive, <u16 as Archive>::Archived: Deserialize<u16, __D>, bool: Archive, <bool as Archive>::Archived: Deserialize<bool, __D>, Option<ContextIdMap>: Archive, <Option<ContextIdMap> as Archive>::Archived: Deserialize<Option<ContextIdMap>, __D>, Schema: Archive, <Schema as Archive>::Archived: Deserialize<Schema, __D>, Option<ModelInfo>: Archive, <Option<ModelInfo> as Archive>::Archived: Deserialize<Option<ModelInfo>, __D>,

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

Deserializes using the given deserializer

impl Serialize for Metadata

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

where __S: Serializer,

Serialize this value into the given Serde serializer.

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

where String: Serialize<__S>, i16: Serialize<__S>, u16: Serialize<__S>, bool: Serialize<__S>, Option<ContextIdMap>: Serialize<__S>, Schema: Serialize<__S>, Option<ModelInfo>: 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.
