Struct NegotiatedExtensionSet 

pub struct NegotiatedExtensionSet { /* private fields */ }

Frozen per-request extension state derived from both peers’ current settings.

Implementations

impl NegotiatedExtensionSet

pub const fn registry_receipt(&self) -> &ExtensionRegistryReceipt

Returns the registry receipt that this set is bound to.

pub const fn protocol_era(&self) -> ProtocolEra

Returns the exact modern protocol era that produced this request state.

pub fn active(&self, id: &ExtensionId) -> Option<&NegotiatedExtension>

Returns a negotiated extension when it is active for this exchange.

pub fn inactive_reason( &self, id: &ExtensionId, ) -> Option<ExtensionInactiveReason>

Returns the recorded non-activating outcome for a registered descriptor.

pub fn active_extensions( &self, ) -> impl ExactSizeIterator<Item = &NegotiatedExtension>

Returns enabled descriptors in deterministic identifier order.

pub fn mcp_apps_activation_receipt( &self, registry: &ExtensionDescriptorRegistry, ) -> Option<McpAppsActivationReceipt>

Derives the sole receipt accepted by the Apps Host/View bridge for this current negotiated exchange.

The receipt is unavailable for a legacy exchange, a different frozen registry, inactive Apps settings, or any descriptor that differs from the frozen official method-free Apps descriptor.

pub const fn unknown_client_extensions( &self, ) -> &BTreeMap<ExtensionId, ExtensionSettings>

Returns unknown current-message client settings preserved only for diagnostics.

pub const fn unknown_server_extensions( &self, ) -> &BTreeMap<ExtensionId, ExtensionSettings>

Returns unknown server discovery settings preserved only for diagnostics.

impl NegotiatedExtensionSet

pub fn admit_capability<'a>( &self, registry: &'a ExtensionDescriptorRegistry, request_era: ProtocolEra, capability: &ExtensionId, ) -> Result<&'a ExtensionDescriptor, ExtensionDispatchError>

Admits an active extension capability for one modern request.

pub fn admit_method<'a>( &self, registry: &'a ExtensionDescriptorRegistry, request_era: ProtocolEra, capability: &ExtensionId, name: &str, direction: ExtensionDirection, ) -> Result<&'a ExtensionDescriptor, ExtensionDispatchError>

Admits a method owned by an active capability for one modern request.

pub fn admit_notification<'a>( &self, registry: &'a ExtensionDescriptorRegistry, request_era: ProtocolEra, capability: &ExtensionId, name: &str, direction: ExtensionDirection, ) -> Result<&'a ExtensionDescriptor, ExtensionDispatchError>

Admits a notification owned by an active capability for one modern request.

pub fn admit_result_discriminator<'a>( &self, registry: &'a ExtensionDescriptorRegistry, request_era: ProtocolEra, capability: &ExtensionId, discriminator: &str, ) -> Result<&'a ExtensionDescriptor, ExtensionDispatchError>

Admits a result discriminator owned by an active capability for one modern request.
