Struct SchemaMapper 

pub struct SchemaMapper {
    pub source_schema: DatasetSchema,
    /* private fields */
}

Maps dataset-specific labels to canonical types.

Fields

source_schema: DatasetSchema

The source dataset schema

Implementations

impl SchemaMapper

pub fn for_dataset(schema: DatasetSchema) -> Self

Create a mapper for a specific dataset.

pub fn to_canonical(&self, label: &str) -> CanonicalType

Map a dataset label to canonical type.

pub fn information_loss(&self, label: &str) -> Option<&InformationLoss>

Get information loss for a label (if any).

pub fn to_entity_type(&self, label: &str) -> EntityType

Map to EntityType for compatibility with existing code.

pub fn all_losses(&self) -> impl Iterator<Item = &InformationLoss>

Get all mappings that have information loss.

pub fn label_overlap(&self, other: &SchemaMapper) -> f64

Calculate label overlap with another schema.

Used to detect if “zero-shot” evaluation is actually fair. High overlap (>80%) means evaluation inflates scores.

Trait Implementations

impl Clone for SchemaMapper

fn clone(&self) -> SchemaMapper

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for SchemaMapper

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

Formats the value using the given formatter.
