Direction-sensitive extension dispatch failure.

Variants

LegacyProtocolExcluded

Extensions are excluded from an exact MCP 2024-11-05 request.

ProtocolEraMismatch

The request era does not match the immutable era that negotiated this set.

Fields

negotiated: ProtocolEra

The exact era that created this set.

request: ProtocolEra

The exact era attached to the request being admitted.

RegistryReceiptMismatch

Dispatch used a registry other than the frozen registry that negotiated the set.

InactiveCapability(String)

The named extension was not activated by developer opt-in and bilateral negotiation.

CapabilityDoesNotOwn

The active capability does not own the named request member.

Fields

capability: String

Active extension capability identifier.

field: &'static str

Registered member category.

value: String

Request-supplied member spelling.

NameTooLong(String)

The caller supplied an unbounded member name.

NoActiveOwner

No active extension owns the requested member in this direction.

Fields

field: &'static str

value: String

DirectionMismatch

An owner exists but is declared in the opposite direction.

Fields

field: &'static str

value: String

expected: ExtensionDirection

actual: ExtensionDirection

AmbiguousActiveOwner

A registry invariant was violated by more than one active owner.

Fields

field: &'static str

value: String

Trait Implementations

impl Clone for ExtensionDispatchError

fn clone(&self) -> ExtensionDispatchError

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for ExtensionDispatchError

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Display for ExtensionDispatchError

fn fmt(&self, formatter: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Eq for ExtensionDispatchError

impl Error for ExtensionDispatchError

fn source(&self) -> Option<&(dyn Error + 'static)>

Returns the lower-level source of this error, if any.

fn description(&self) -> &str

👎Deprecated since 1.42.0:

use the Display impl or to_string()

fn cause(&self) -> Option<&dyn Error>

👎Deprecated since 1.33.0:

replaced by Error::source, which can support downcasting

fn provide<'a>(&'a self, request: &mut Request<'a>)

🔬This is a nightly-only experimental API. (error_generic_member_access)

Provides type-based access to context intended for error reports.

impl PartialEq for ExtensionDispatchError

fn eq(&self, other: &ExtensionDispatchError) -> bool

Equality operator ==.

fn ne(&self, other: &Rhs) -> bool

Inequality operator !=.
