Struct ContextIdMap 

pub struct ContextIdMap {
    pub left: Vec<u16>,
    pub right: Vec<u16>,
}

A pair of context-ID permutations, perm[old_id] = new_id.

left permutes left-context IDs (a word’s left_id, the connection matrix’s backward / row axis, length backward_size) and right permutes right-context IDs (a word’s right_id, the forward / column axis, length forward_size). Both are bijections over 0..len, with ID 0 pinned to 0 because it is reserved for BOS/EOS.

Fields

left: Vec<u16>

Permutation of left-context IDs (WordEntry.left_id, matrix backward axis).

right: Vec<u16>

Permutation of right-context IDs (WordEntry.right_id, matrix forward axis).

Implementations

impl ContextIdMap

pub fn map_left(&self, id: u16) -> u16

Map a left-context ID into the remapped space.

Arguments

• id - Left-context ID in the original space.

Returns

The remapped ID, or id unchanged when it is outside the permutation (a malformed ID; the matrix build rejects those separately).

pub fn map_right(&self, id: u16) -> u16

Map a right-context ID into the remapped space.

Arguments

• id - Right-context ID in the original space.

Returns

The remapped ID, or id unchanged when it is outside the permutation.

Trait Implementations

impl Archive for ContextIdMap

where Vec<u16>: 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 = ArchivedContextIdMap

The archived representation of this type.

type Resolver = ContextIdMapResolver

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 ContextIdMap

fn clone(&self) -> ContextIdMap

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ContextIdMap

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for ContextIdMap

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<ContextIdMap, __D> for Archived<ContextIdMap>

where Vec<u16>: Archive, <Vec<u16> as Archive>::Archived: Deserialize<Vec<u16>, __D>,

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

Deserializes using the given deserializer

impl Serialize for ContextIdMap

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 ContextIdMap

where Vec<u16>: 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.
