Struct StorageError 

pub struct StorageError { /* private fields */ }

Storage layer error type

Design principles:

1. Small size: Uses boxed errors to keep struct size minimal (~24 bytes)
2. Full context: Preserves error chain
3. Clone support: Can be cloned for logging/propagation

Implementations

impl StorageError

pub fn new(kind: StorageErrorKind, message: impl Into<String>) -> StorageError

pub fn with_source(self, source: Box<dyn Error + Sync + Send>) -> StorageError

pub fn kind(&self) -> StorageErrorKind

pub fn message(&self) -> &str

pub fn source(&self) -> &Option<Box<dyn Error + Sync + Send>>

pub fn is_retryable(&self) -> bool

pub fn db_error(message: impl Into<String>) -> StorageError

pub fn storage_error(message: impl Into<String>) -> StorageError

pub fn serialize_error(message: impl Into<String>) -> StorageError

pub fn deserialize_error(message: impl Into<String>) -> StorageError

pub fn node_not_found(value: VertexId) -> StorageError

pub fn edge_not_found(value: VertexId) -> StorageError

pub fn not_supported(message: impl Into<String>) -> StorageError

pub fn conflict(message: impl Into<String>) -> StorageError

pub fn write_write_conflict(entity: impl Into<String>) -> StorageError

A write-write conflict detected at the storage layer write path.

Two writes touched the same entity with incompatible timestamps (e.g. deleting an edge that another write already deleted at a different timestamp). This is the first line of defense; the transaction layer’s commit-time WriteSet certification remains the fallback.

Trait Implementations

impl Clone for StorageError

fn clone(&self) -> StorageError

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for StorageError

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

Formats the value using the given formatter.

impl Display for StorageError

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

fn description(&self) -> &str

👎Deprecated since 1.42.0:

use the Display impl or to_string()
