Enum ProtocolErrorCode 

pub enum ProtocolErrorCode {
    InvalidRequest,
    NotFound,
    InterfaceNotFound,
    InterfaceMismatch,
    OperationNotFound,
    InvalidArguments,
    ValidatorRequired,
    ValidatorMismatch,
    InterfaceValidatorRequired,
    InterfaceValidatorMismatch,
    PermissionDenied,
    ResourceLimitExceeded,
    Internal,
    OperationOutcomeUnknown,
}

Stable protocol failure code returned by a host.

This is the complete wire-level code set. A Client treats a malformed success or failure response, including a code disallowed for its interaction, as a Client-local InvalidResponse. An unsupported descriptor format is likewise a Client-local UnsupportedDescriptorFormat; neither condition is a code a Host can return.

Variants

InvalidRequest

The request is structurally invalid before an operation descriptor is fixed.

NotFound

The target object is not published.

InterfaceNotFound

The interface reference is not currently published.

InterfaceMismatch

The selected interface is not on the current object.

OperationNotFound

The selected operation is not declared by the current interface.

InvalidArguments

Supplied arguments do not match the fixed operation declaration.

ValidatorRequired

The operation requires an object validator and none was supplied.

ValidatorMismatch

The supplied object validator does not match current state.

InterfaceValidatorRequired

A mutable interface requires its validator and none was supplied.

InterfaceValidatorMismatch

The supplied interface validator does not match the descriptor.

PermissionDenied

A published operation is not permitted for the caller.

ResourceLimitExceeded

A bounded protocol resource limit was exceeded.

For call_operation, the Host guarantees that the operation was not run or that all of its effects were rolled back.

Internal

The Host encountered an internal failure.

For call_operation, the Host guarantees that the operation was not run or that all of its effects were rolled back.

OperationOutcomeUnknown

The Host cannot guarantee that the operation was not run or rolled back.

A Client must not automatically retry because the operation may have committed effects even though no success response was available.

Implementations

impl ProtocolErrorCode

pub const ALL: [Self; 14]

Every canonical wire-level error code.

pub const fn is_allowed_for(self, interaction: ProtocolInteraction) -> bool

Whether a Host may return this code for interaction.

false identifies an invalid error response; it does not turn that response into another wire-level protocol failure.
