Struct CompositeBlocker 

pub struct CompositeBlocker { /* private fields */ }

Composite blocker that applies multiple blocking keys.

For cross-schema linkage, source_remaps stores per-source field-name translations (b_field to a_field). Before key extraction, any record whose source label has an entry in source_remaps gets its fields renamed to the canonical (A-side) names so the existing BlockingKey implementations can extract values without knowing about schema differences.

Implementations

impl CompositeBlocker

pub fn new() -> Self

pub fn add(self, key: impl BlockingKey + 'static) -> Self

pub fn add_boxed(self, key: Box<dyn BlockingKey>) -> Self

pub fn with_source_remap( self, source: impl Into<String>, remap: HashMap<String, String>, ) -> Self

Register a field-name remap for records from source.

remap maps b_field to a_field so that the source-B fields are visible under canonical source-A names during blocking key extraction.

Trait Implementations

impl Blocker for CompositeBlocker

fn blocking_keys(&self, record: &Record, schema: &Schema) -> Vec<String>

fn index_record( &self, record: &Record, schema: &Schema, index: &mut dyn BlockIndex, )

fn candidates( &self, record: &Record, schema: &Schema, index: &dyn BlockIndex, ) -> Vec<RecordId>

impl Default for CompositeBlocker

fn default() -> Self

Returns the “default value” for a type.
