Struct MicrokernelServer

Source 
pub struct MicrokernelServer<P: OAuthProviderTrait<S, DefaultClientManager<S>> + 'static, S: OAuthStorage + Clone + 'static, M: McpServerHandler = McpServer> { /* private fields */ }
Expand description

Microkernel server builder that composes independent handlers

This builder demonstrates the microkernel principle where services are composed from independent, single-responsibility components. Now supports any OAuth provider, storage backend, and MCP server through trait abstraction.
