Enum CapabilityMutationError 

pub enum CapabilityMutationError {
    NotRegistered {
        component_id: ComponentId,
    },
    UndeclaredNeed {
        component_id: ComponentId,
        request: CapabilityRequest,
    },
    AlreadyGranted {
        current: Grant,
    },
    SynchronizationPoisoned,
}

A typed current-state refusal from the host grant table.

Variants

NotRegistered

The identity has no current registered incarnation.

Fields

component_id: ComponentId

Missing or removed identity.

UndeclaredNeed

The requested row was absent from the component manifest.

Fields

component_id: ComponentId

Component that would receive authority.

request: CapabilityRequest

Exact row refused by the host.

AlreadyGranted

The exact row already exists; provenance identifies its current state.

Fields

current: Grant

Active row observed at the mutation point.

SynchronizationPoisoned

Grant table synchronization was poisoned by a panic.

impl Eq for CapabilityMutationError

impl Error for CapabilityMutationError

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
