CNotImplementedException	Thrown whenever a procedure must abort due to not being implemented
COpenAssetIOException	Exception base for all OpenAssetIO exceptions
CUnhandledException	Exceptions emitted from manager plugins that are not handled will be converted to this type and re-thrown when the exception passes through the OpenAssetIO middleware

▼CManager	The Manager is the Host facing representation of an Asset Management System
▼CBatchElementErrorPolicyTag	Tag dispatching structure intended for use selecting appropriate overloads for various error-handling modes
CException	Exception policy overloads, when used in a batch context, will emit an exception at the first encountered errors::BatchElementError provided by the ManagerInterface
CVariant	Variant policy overloads, when used in a batch context, will be exhaustive for all elements in the batch, a variant result containing either a trait::TraitsData or errors::BatchElementError will be provided for each EntityReference provided as an argument to the operation
▼CManagerFactory	The ManagerFactory is the primary mechanism for querying for available managers and constructing a Manager
CManagerDetail	Simple struct containing the default configuration details of a potential manager implementation
CManagerImplementationFactoryInterface	Manager Factories are responsible for instantiating classes that derive from openassetio::v1::managerApi::ManagerInterface for use within a host
