Struct IndicatorRegistry 

pub struct IndicatorRegistry { /* private fields */ }

Runtime registry mapping indicator names to their factory functions.

Analogous to IndicatorRegistry._indicators: dict[str, type[Indicator]] in Python.

Implementations

impl IndicatorRegistry

pub fn new_uninit() -> Self

pub fn register(&self, name: &str, factory: IndicatorFactory)

Register an indicator factory under name (lowercased).

Mirrors IndicatorRegistry.register(indicator_cls).

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

List all registered indicator names.

Mirrors IndicatorRegistry.list() -> list[str].

pub fn get(&self, name: &str) -> Option<IndicatorFactory>

Look up a factory by name (case-insensitive).

Mirrors IndicatorRegistry.get(name).

pub fn create( &self, name: &str, params: &HashMap<String, String>, ) -> Result<Box<dyn Indicator>, IndicatorError>

Create an indicator instance by name.

Mirrors IndicatorRegistry.create(name, **params) and IndicatorFactory.create(name, **params).

Errors

• IndicatorError::UnknownIndicator if name is not registered.
• Propagates construction errors from the factory.

pub fn contains(&self, name: &str) -> bool

Check whether an indicator name is registered.

Mirrors indicator_registry.get(name) is not None in IndicatorFactory.validate_config().
