Overview

Internal registry for storing providers and tracking shutdown order.

Key format:

• "Type" → default concrete registration
• "Type:name" → named concrete registration
• "~Type:Impl" → interface binding (unnamed)
• "~Type:Impl:name" → interface binding (named)

Thread-safe for multi-threaded Crystal (-Dpreview_mt).

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.

• #find_all_by_name(interface_type : String, name : String) : Array(Provider::Base)

  Find all named interface providers matching ~Type:Impl:name pattern.

• #find_all_by_name_keyed(interface_type : String, name : String) : Hash(String, Provider::Base)

  Find all named interface providers keyed by full key.

• #find_by_name(interface_type : String, name : String) : Provider::Base

  Find a named interface provider by scanning for ~Type:Impl:name pattern.

• #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.

• #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.
