Enum CatalogError 

pub enum CatalogError {
    StaleVersion {
        collection: CollectionId,
        range_id: RangeId,
        current: CatalogVersion,
        attempted: CatalogVersion,
    },
    ShardKeyModeMismatch {
        collection: CollectionId,
        declared: ShardKeyMode,
        attempted: ShardKeyMode,
    },
    OverlappingRange {
        collection: CollectionId,
        existing: RangeId,
        attempted: RangeId,
    },
}

Why a catalog update was rejected.

Variants

StaleVersion

The update’s version did not strictly advance the range’s current version — a stale or out-of-order write. Carries both versions so the caller (or a replica) can see how far behind it was.

Fields

collection: CollectionId

range_id: RangeId

current: CatalogVersion

attempted: CatalogVersion

ShardKeyModeMismatch

The entry’s shard key mode disagrees with the collection’s declared mode. A collection is hash- or ordered-partitioned, never both.

Fields

collection: CollectionId

declared: ShardKeyMode

attempted: ShardKeyMode

OverlappingRange

Creating this range would overlap an existing range of the same collection, which would make routing ambiguous.

Fields

collection: CollectionId

existing: RangeId

attempted: RangeId

Trait Implementations

impl Clone for CatalogError

fn clone(&self) -> CatalogError

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for CatalogError

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

Formats the value using the given formatter.

impl Display for CatalogError

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

Formats the value using the given formatter.

impl Eq for CatalogError

impl Error for CatalogError

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 CatalogError

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

Tests for self and other values to be equal, and is used by ==.

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

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
