class Di::Registry

• Di::Registry
• Reference
• Object

Overview

Internal registry for storing providers and tracking shutdown order. Uses a string key format: "TypeName" for default, "TypeName/name" for named providers. For interface bindings, uses "TypeName:ImplName" to allow multiple implementations. Thread-safe for multi-threaded Crystal (-Dpreview_mt).

Defined in:

di/registry.cr

Class Method Summary

• .interface_key(interface_type : String, impl_type : String) : String

  Build an interface binding key from interface and implementation types.

• .key(type_name : String, service_name : String | Nil = nil) : String

  Build a registry key from type name and optional service name.

Instance Method Summary

• #clear : Nil

  Clear all providers and reset order.

• #count_implementations(interface_type : String) : Int32

  Count implementations for an interface type.

• #delete(key : String) : Nil

  Remove a provider by key (used for rollback on partial registration failure).

• #each(& : String, Provider::Base -> )

  Iterate over all providers with their keys.

• #get(key : String) : Provider::Base

  Get a provider by key, raising ServiceNotFound if not registered.

• #get?(key : String) : Provider::Base | Nil

  Get a provider by key, or nil if not registered.

• #get_all(interface_type : String) : Array(Provider::Base)

  Get all providers for an interface type (keys starting with "Type:").

• #get_all_keyed(interface_type : String) : Hash(String, Provider::Base)

  Get all providers keyed by full key for deduplication in child scopes.

• #implementation_names(interface_type : String) : Array(String)

  Get implementation names for an interface type.

• #order : Array(String)

  Return all registered keys in registration order.

• #register(key : String, provider : Provider::Base) : Nil

  Register a provider with the given key.

• #register_interface(interface_type : String, impl_type : String, provider : Provider::Base) : Nil

  Register an interface binding with implementation tracking.

• #registered?(key : String) : Bool

  Check if a provider is registered for the given key.

• #reverse_order : Array(String)

  Return all registered keys in reverse order (for shutdown).

• #size : Int32

  Number of registered providers.

• #snapshot : Hash(String, Provider::Base)

  Return a snapshot of all providers for iteration without holding mutex.
