Enum MetadataViewError 

pub enum MetadataViewError {
    MissingManifest {
        namespace_id: NamespaceId,
    },
    MaintenanceRequired {
        namespace_id: NamespaceId,
        reason: String,
    },
    SnapshotUnavailable {
        requested_seq: ChangeSeq,
        head_seq: ChangeSeq,
    },
}

Failures specific to manifest-plus-tail metadata views.

These are not generic store failures: each variant names the recovery or caller action we expect. Normal reads and publishes must return these errors instead of falling back to a whole-namespace rebuild.

Trait Implementations

impl Clone for MetadataViewError

fn clone(&self) -> MetadataViewError

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for MetadataViewError

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

Formats the value using the given formatter.

impl Display for MetadataViewError

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

Formats the value using the given formatter.

impl Error for MetadataViewError

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 From<MetadataViewError> for CoreError

fn from(source: MetadataViewError) -> Self

Converts to this type from the input type.
