Implementations

impl StorageError

pub fn not_found<T: Into<ResourceId>>( resource_type: ResourceType, resource_id: T, ) -> Self

Create a not found error with resource type and ID

pub fn constraint_violation<S: Into<String>>(message: S) -> Self

Create a constraint violation error

pub fn validation<S: Into<String>>(message: S) -> Self

Create a validation error

pub fn encryption<S: Into<String>>(message: S) -> Self

Create an encryption error

pub fn migration<S: Into<String>>(message: S) -> Self

Create a migration error

pub fn backup<S: Into<String>>(message: S) -> Self

Create a backup error

pub fn is_not_found(&self) -> bool

Check if this is a not found error

pub fn is_constraint_violation(&self) -> bool

Check if this is a constraint violation error

pub fn is_validation_error(&self) -> bool

Check if this is a validation error

pub fn is_database_error(&self) -> bool

Check if this is a database error

pub fn resource_type(&self) -> Option<&ResourceType>

Get the resource type if this is a not found error

pub fn resource_id(&self) -> Option<&ResourceId>

Get the resource ID if this is a not found error

pub fn is_retryable(&self) -> bool

Check if the error is retryable (transient database errors)

Trait Implementations

impl Debug for StorageError

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

Formats the value using the given formatter.

impl Display for StorageError

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

Formats the value using the given formatter.

impl Error for StorageError

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<Error> for StorageError

fn from(source: Error) -> Self

Converts to this type from the input type.

impl From<Error> for StorageError

fn from(source: Error) -> Self

Converts to this type from the input type.
