Repository error types

Variants

NotFound

AlreadyExists(String)

ValidationError(String)

DatabaseError(String)

SerializationError(String)

Conflict(String)

InternalError(String)

Violations(Vec<Violation>)

The database refused the write through a constraint that stands for a rule: a foreign key, a CHECK, a generated unique index or an exclusion. One violation, coded as the application-side check is.

Implementations

impl RepositoryError

pub fn from_source(e: impl Into<Error>) -> Self

The repository error for a failure an inner layer reported as any error type. A backbone_orm::QueryParamError inside it (a list parameter the request got wrong) becomes one invalid_query violation on that parameter. A database error inside it (however wrapped in context) converts as a sqlx::Error does, so a constraint the database refused with stays a violation; anything else keeps its sentence as a database error.

pub fn from_batch_source(e: impl Into<Error>) -> Self

from_source for a batch write: when the failure is a backbone_orm::BatchItemError, the error is placed on the item that failed (see at_batch_index).

pub fn at_batch_index(self, index: usize) -> Self

Place this error on item index of a batch: a violation’s path gains the index as its first segment (3/name, or 3 for a whole-record rule), and any other error’s sentence names the item.

Trait Implementations

impl Debug for RepositoryError

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

Formats the value using the given formatter.

impl Display for RepositoryError

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

Formats the value using the given formatter.

impl Error for RepositoryError

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.
