Struct TypeMappingRegistry 

pub struct TypeMappingRegistry { /* private fields */ }

Registry of type mappings

Maintains mappings for all known types (built-in and user-defined). Thread-safe for concurrent access.

Implementations

impl TypeMappingRegistry

pub fn new() -> Self

Create a new empty registry

NOTE: No built-in types are registered. Finance-specific types like “Candle” should be registered at CLI/application startup from stdlib.

pub fn register(&self, type_name: &str, mapping: TypeMapping)

Register a type mapping

Arguments

• type_name - Name of the type
• mapping - TypeMapping specifying required columns

pub fn get(&self, type_name: &str) -> Option<TypeMapping>

Get type mapping by name

Arguments

• type_name - Type name to lookup

Returns

TypeMapping if found, None otherwise

pub fn has(&self, type_name: &str) -> bool

Check if a type mapping exists

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

List all registered type names

pub fn unregister(&self, type_name: &str) -> bool

Unregister a type mapping

pub fn clear(&self)

Clear all type mappings
