Errors returned by the explicit polyglot persistence boundary.

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.

InvalidIdentifier

A collection, database, namespace, or document identifier was rejected.

Fields

kind: &'static str

Identifier category.

reason: &'static str

Stable, credential-free failure detail.

InvalidConfiguration

An adapter configuration is unsafe or incomplete.

Fields

backend: &'static str

Backend being configured.

reason: &'static str

Stable, credential-free failure detail.

Conflict

A record with the requested identifier already exists.

NotFound

A record required by a mutating operation does not exist.

Serialization(String)

A model could not be serialized or decoded.

Driver

A backend driver returned an error.

Fields

backend: &'static str

Backend that returned the error.

message: String

Error text with secrets excluded by the adapter.

ResponseTooLarge

A response exceeded the adapter’s configured memory bound.

Fields

backend: &'static str

Backend that returned the response.

limit_bytes: usize

Maximum accepted response size.

UnsupportedValue

The backend cannot represent a value through the portable API.

Fields

backend: &'static str

Backend that produced the value.

kind: String

Backend type name.

Worker

Work delegated to a blocking worker could not complete.

Fields

backend: &'static str

Backend whose worker stopped.

message: String

Join or lock failure detail.

Trait Implementations

impl Debug for PolyglotError

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

Formats the value using the given formatter.

impl Display for PolyglotError

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

Formats the value using the given formatter.

impl Error for PolyglotError

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<PolyglotError> for DocumentRecoveryError

fn from(error: PolyglotError) -> Self

Converts to this type from the input type.
