Implementations

impl BlockerFactory

pub fn from_schema(schema: &Schema) -> CompositeBlocker

Build a CompositeBlocker whose blocking keys are chosen automatically from the Schema’s FieldKind annotations.

Priority rules (applied in order):

• 2+ Name fields + Date: uses PhoneticNameDobInitialKey (surname phonetic + first-name initial + DOB year)
• 1 Name field + Date: uses PhoneticNameDobKey (surname phonetic + DOB year)
• Name + Address: uses AddressInitialKey (first address token + first name initial)
• Phone: adds SuffixKey(7) on the first Phone field
• Id: adds SuffixKey(4) on each Id field
• Date only (no Name): adds DateFragmentKey(YearMonth) on the first Date field
• Categorical: adds ExactFieldKey on each Categorical field

pub fn from_custom_category( schema: &Schema, cat: CustomSchemaCategory, ) -> CompositeBlocker

Build a CompositeBlocker from a user-defined CustomSchemaCategory.

Each rule in the category is applied in order against schema’s FieldKind annotations. Rules that reference field kinds not present in the schema are silently skipped, no panic, no empty blocker.

pub fn from_schema_category( schema: &Schema, category: SchemaCategory, ) -> CompositeBlocker

Build a CompositeBlocker tuned for a specific domain category.

Keys are chosen based on both the category semantics and the FieldKind annotations present in schema.
