Resource handler trait for managing resources

Required Methods

fn read_resource<'life0, 'async_trait>( &'life0 self, request: ReadResourceRequest, ) -> Pin<Box<dyn Future<Output = MCPResult<ReadResourceResponse>> + Send + 'async_trait>>

where Self: 'async_trait, 'life0: 'async_trait,

Read a resource

fn list_resources<'life0, 'async_trait>( &'life0 self, request: ListResourcesRequest, ) -> Pin<Box<dyn Future<Output = MCPResult<ListResourcesResponse>> + Send + 'async_trait>>

where Self: 'async_trait, 'life0: 'async_trait,

List available resources

fn list_resource_templates<'life0, 'async_trait>( &'life0 self, request: ListResourceTemplatesRequest, ) -> Pin<Box<dyn Future<Output = MCPResult<ListResourceTemplatesResponse>> + Send + 'async_trait>>

where Self: 'async_trait, 'life0: 'async_trait,

List resource templates

fn validate_resource_access<'life0, 'life1, 'life2, 'async_trait>( &'life0 self, uri: &'life1 str, operation: RootOperation, roots: &'life2 [Root], ) -> Pin<Box<dyn Future<Output = MCPResult<()>> + Send + 'async_trait>>

where Self: 'async_trait, 'life0: 'async_trait, 'life1: 'async_trait, 'life2: 'async_trait,

Validate resource access against roots (optional implementation) According to MCP specification, roots are informational and not strictly enforcing. This method provides advisory validation but does not block access if no root matches.
