Enum TableStoreError 

#[non_exhaustive]
pub enum TableStoreError {
    ConcurrencyConflict {
        collection: String,
        id: String,
        expected: u64,

    NotFound {

    Lock(LockError),

}

Error type for table-store and read-model operations.

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

ConcurrencyConflict

Optimistic concurrency conflict.

Fields

collection: String

id: String

expected: u64

actual: u64

Serde(String)

Serialization/deserialization error.

Storage(String)

Storage-level error.

BackendStorage

Backend storage failure with its retry classification preserved.

SQL adapters use this instead of flattening a driver error into Storage, because projector runners must distinguish a transient busy/deadlock/connection failure from a deterministic fault before deciding whether terminal failure evidence may be recorded.

Fields

operation: String

retryable: bool

message: String

CausalWriteRequired

A raw/legacy write targeted a table registered to the causal projection protocol and therefore cannot mint the required revision evidence.

Fields

table: String

NotFound

Row not found.

Fields

collection: String

id: String

Lock(LockError)

Lock error.

Metadata(String)

Schema/metadata error.

Trait Implementations

impl Clone for TableStoreError

fn clone(&self) -> TableStoreError

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for TableStoreError

impl Eq for TableStoreError

impl Error for TableStoreError

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
