Struct Schema 

pub struct Schema {
    pub fields: Vec<String>,
    /* private fields */
}

Dictionary schema that defines the structure of dictionary entries

Fields

fields: Vec<String>

All field names including common fields (surface, left_context_id, right_context_id, cost, …)

Implementations

impl Schema

pub fn new(fields: Vec<String>) -> Self

Create a new dictionary schema

pub fn get_field_index(&self, field_name: &str) -> Option<usize>

Get field index by name

pub fn field_count(&self) -> usize

Get total field count

pub fn get_field_name(&self, index: usize) -> Option<&str>

Get field name by index

pub fn get_custom_fields(&self) -> &[String]

Get custom fields (index >= 4)

pub fn get_all_fields(&self) -> &[String]

Get all fields

pub fn validate_fields(&self, row: &StringRecord) -> LinderaResult<()>

Validate that CSV row has all required fields

impl Schema

pub fn get_field_by_name(&self, name: &str) -> Option<FieldDefinition>

Find field by name (backward compatibility)

Trait Implementations

impl Archive for Schema

where Vec<String>: Archive, Option<HashMap<String, usize>>: 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 = ArchivedSchema

The archived representation of this type.

type Resolver = SchemaResolver

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 Schema

fn clone(&self) -> Schema

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Schema

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

Formats the value using the given formatter.

impl Default for Schema

fn default() -> Self

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for Schema

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<Schema, __D> for Archived<Schema>

where Vec<String>: Archive, <Vec<String> as Archive>::Archived: Deserialize<Vec<String>, __D>, Option<HashMap<String, usize>>: Archive, <Option<HashMap<String, usize>> as Archive>::Archived: Deserialize<Option<HashMap<String, usize>>, __D>,

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

Deserializes using the given deserializer

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

where Vec<String>: Serialize<__S>, Option<HashMap<String, usize>>: 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.

impl Serialize for Schema

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

where __S: Serializer,

Serialize this value into the given Serde serializer.
