Struct JsSchema 

pub struct JsSchema { /* private fields */ }

Dictionary schema definition.

Defines the structure and fields of dictionary entries.

Implementations

impl JsSchema

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

Creates a new schema with the specified field names.

Arguments

• fields - Array of field name strings.

pub fn create_default() -> Self

Creates a default schema matching the IPADIC format (13 fields).

Returns

A schema with the standard IPADIC field definitions.

pub fn fields(&self) -> Vec<String>

Returns the field names in the schema.

pub fn get_field_index(&self, field_name: String) -> Option<u32>

Returns the index of the specified field name.

Arguments

• field_name - Name of the field to look up.

Returns

The zero-based index of the field, or undefined if not found.

pub fn field_count(&self) -> u32

Returns the total number of fields in the schema.

pub fn get_field_name(&self, index: u32) -> Option<String>

Returns the field name at the specified index.

Arguments

• index - Zero-based index.

Returns

The field name, or undefined if the index is out of range.

pub fn get_custom_fields(&self) -> Vec<String>

Returns the custom fields (index 4 and above).

Returns

An array of custom field names.

pub fn get_all_fields(&self) -> Vec<String>

Returns all field names in the schema.

Returns

An array of all field names.

pub fn get_field_by_name(&self, name: String) -> Option<JsFieldDefinition>

Returns the field definition for the specified field name.

Arguments

• name - Name of the field to look up.

Returns

The field definition, or undefined if not found.

pub fn validate_record(&self, record: Vec<String>) -> Result<()>

Validates that a CSV record matches the schema.

Arguments

• record - Array of field values to validate.
