Struct CoreSchema 

pub struct CoreSchema { /* private fields */ }

Dictionary schema shared by the bindings.

Owns the field storage, the name-to-index map, and the field lookups by delegating to lindera::dictionary::Schema, so each binding can wrap a CoreSchema instead of reimplementing the same logic.

Implementations

impl CoreSchema

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

Creates a schema from the given ordered field names.

pub fn create_default() -> Self

Creates the default binding schema (see default_dictionary_fields).

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

Returns all field names in order.

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

Returns the index of field_name, if present.

pub fn field_count(&self) -> usize

Returns the total number of fields.

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

Returns the field name at index, if present.

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

Returns the custom fields (everything after the four system fields).

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

Returns the CoreFieldDefinition for name, if present.

pub fn validate_record(&self, record: &[String]) -> CoreResult<()>

Validates a CSV record against this schema.

Returns an ErrorKind::Validation error when the record has too few fields or a required field is empty.

pub fn as_lindera(&self) -> &Schema

Borrows the backing lindera schema.

pub fn into_lindera(self) -> Schema

Consumes this schema and returns the backing lindera schema.
