Enum RoutingError 

pub enum RoutingError {
    TabletMoved {
        tablet_id: TabletId,
        used_generation: u64,
        current_generation: u64,
    },
    TabletSplit {
        tablet_id: TabletId,
        used_generation: u64,
        current_generation: u64,
    },
    StaleMetadata {
        tablet_id: TabletId,
        used_generation: u64,
        current_generation: u64,
    },
}

A request arrived with a tablet generation that no longer matches (spec section 12.4). The gateway refreshes metadata and retries safe operations.

Variants

TabletMoved

The tablet moved (or retired); refresh routing metadata.

Fields

tablet_id: TabletId

The tablet the request targeted.

used_generation: u64

Generation the request was routed with.

current_generation: u64

Generation the replica now holds.

TabletSplit

The tablet is mid-split; retry once the split publishes.

Fields

tablet_id: TabletId

The tablet the request targeted.

used_generation: u64

Generation the request was routed with.

current_generation: u64

Generation the replica now holds.

StaleMetadata

The request’s routing metadata is stale for any other reason.

Fields

tablet_id: TabletId

The tablet the request targeted.

used_generation: u64

Generation the request was routed with.

current_generation: u64

Generation the replica now holds.

Implementations

impl RoutingError

pub fn category(&self) -> ErrorCategory

The stable error category the gateway maps this onto (spec sections 9.7, 12.4); all three refresh routing metadata and retry safe operations.

Trait Implementations

impl Clone for RoutingError

fn clone(&self) -> RoutingError

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for RoutingError

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

Formats the value using the given formatter.

impl Display for RoutingError

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

Formats the value using the given formatter.

impl Eq for RoutingError

impl Error for RoutingError

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 RoutingError

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

Equality operator ==.

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

Inequality operator !=.
